I've been trying to research the other charging networks available and am a little bit lost on what I need or don't need
Assuming that charging at home gets you to and from work, and your other local journeys (i.e. your battery is large enough to cover those) I suggest you use one of the online journey planners to see how you would go about longer distance journeys.

Here's my real-world experience:
I regularly go from East Anglia to Bristol. I can go South, M11, M25 and M4 (charge at Reading), or West-ish to Birmingham (charge there) and down the M5, or cross-country at 45 degrees (charge in Oxford). Journey-time is much of a muchness and I choose based on traffic conditions.
However, charging at any of those places doesn't really give me enough juice to do a round trip from there to Bristol and back to that charger. There is a Supercharger in Bristol, but its out on the West side of the city and 15 minutes or so to get there from city centre, so although I can charge there its not exactly convenient.
So that leads to "destination charging"
The Multi-story carpark I use has a charger, so i can use that. I didn't actually know it was there, first time I visited I spotted it in the car park and so just tried it out. Downloaded the APP (had to walk to office to get WiFi for Phone to do that ...) paid a Deposit (£20), plugged in, waited for the APP to connect ... and abandoned the car to charge.
So in practice that's what I do now because I'm tooled up for it. I have no idea if the next place I want to use will be the same provider (Polar) - probably not - so I'll have the same palaver, setting up an account, the first time I use a new Provider. I suggest you download the Ecotricity APP so you are all set up if you need to charge at one of their sites - I think you get X-charges free annually, as a customer.
The first time I connected in Bristol it probably took me 30 minutes to sort out - including two phone calls to the charging company. The first was a sales call to figure out what Subscription-Plan I needed and the second was because I didn't own a Type-2 cable and thus could only use their 13AMP socket; I couldn't get that to work from their APP so another call to get them to connect it, and then again later on to disconnect it. I doubt I saved any time compared to driving out to the Supercharger!
I now have the right (Type-2) cable ... and the APP installed of course ... but it still takes about 5 minutes to connect - the APP spinner does a countdown in percent ... its painful to watch! However, its convenient ... but nothing like as convenient as Supercharger - Rock up, insert cable, go and have a Pee and get a coffee, come back ... all done
The 13AMP socket I used - gives about 5 miles per hour charge rate. yeah, I was there two days, so that was fine.
The Type-2 cable (at the same facility) about 20 MPH. That's the same as I get at home with my EV charger, so no great shakes. So still looking at 5 - 8 hours charging time - which is fine, I'm there for a full day's work. Price seems quite reasonable (no idea, per kWh, compared to home charging, but seems reasonable "compared to Petrol"
)
A ChaDeMO adaptor gets you about half the speed of Supercharger. Typically the places that have them only have one or two charging stations and no guarantee that they aren't either In-use, or Bust
I drive out of my way to get to Supercharger instead, but if you are in a part of the country with no Supercharger AND destination charging is not sufficient, then definitely ChaDeMO adaptor is the way to go - Type-2 is way too slow for anything other than destination charging.
I have a Commando socket at home (in addition to EV charger), which i have used on a couple of occasions when EV charger has not worked - e.g. couldn't get EV charger to work reliably with a Loaner on one occasion. Don't know where Commando sockets are available - Caravan parks perhaps? so that might be an option for destination charging.
So ... in the car I carry:
The Tesla UMC cable (with adaptors for 13-AMP and Commando)
Type-2 cable (£150-ish)
ChaDeMO (£350 I think?) if you get one I suggest you deliberately do a trial-charge to experience the speed and familiarise yourself with the process before you need it in anger
A very beefy-cable 13AMP extension lead (£20-30) - used when staying with friends for the weekend.
Once you put destination into SatNav the Energy Graph TRIP Tab will show graph of expected and actual, and arrival charge percentage, so you can check that you have enough juice to get there!
Make sure you know what your real world range is. The "government figure" for my car is something ridiculous like 350 miles, real-world is 220 miles - less in Winter / wet / windy conditions. That's when charged to 100% ... so on a regular day when I am charged to 90%, and allowing a 20 mile "buffer", that's a range of 180 miles. I charge to 100% for any journey over 160 miles, and I plan a charging stop for any journey approaching, or over, 200 miles.
Unless making a road-trip I only need me to Supercharge just enough to reach my destination - 10 minutes is 50 miles so on out-and-back days I rarely need more than that to complete my journey.
