I just used ABRP to guestimate your route. This is with settings for my car so yours will be a little different (probably better if your Model 3 is Long Range).
I echo what
@animorph said. Also, I tend to grab food from drive through or carry out as I approach the supercharger and eat in the car if it's not at or near a restaurant. If it is at or near a restaurant I might stay there for a full charge and have a nice sit down meal. Like Texarkana at Olive Garden!
I have actually driven a significant portion of that MANY times. But it's been a couple years and there's new Superchargers for you!
You can either follow the car's routing explicitly, or you can do a little work and make some choices, now that there are more charging locations along this route. Stay at some longer for a bigger charge while you explore the area which might let you skip the next one or just be there a little less time.
Texarkana is at an Olive Garden. It's a much older station and slower, but likely won't be many people there now since they opened the newer one just down the road. And you can have a sit down meal while your car charges!
Little Rock is also older, but it's at an outlet mall! Shopping!
Brinkley is a short walk from a Sonic. Meh. For places like this I usually grab food first and then go to the charger and eat in my car while it charges. Or possibly plug in then get food and walk back to the car to eat. Depends on how long the charge session is supposed to take and how far the food is from the charger.
There are now THREE options in Memphis! One is actually on I-40 and probably best, but the original one (old and slow!) is in a shopping center with a bunch of restaurants.
Jackson TN is at the Casey Jones place. It's a road side attraction and one of a very few sites where I actually saw people being assholes toward Tesla owners. There is also a restaurant here but I've never eaten at it.
Dickson TN is at a hotel. There are a couple restaurants nearby and a Sonic across the road.
There are several in Nashville. Where are you spending the night? It might be good to find a hotel in Nashville that has overnight charging. We stay at the Hermitage which has two plugs (bring your J1772 adapter!) because ... we are hotel snobs
And if you can't charge overnight there are a few superchargers to choose from in the morning. Plugshare can help you filter for plug type and features such as lodging.

Cookeville is WAY off the interstate. I think it's at a Walmart or Target or grocery store or something. There's fast food nearby. I try to skip that site if possible. Charge longer at the preceding one to get past it.
Crossville must be new - I haven't been there. Write a report if you go!
Knoxville on the west side is at a big shopping center. There are a few restaurants, some stores including Target, and a huge parking lot. It's old and slow and there are a lot of people around. It was good during pandemic because no one was there
Knoxville in town I haven't been to - it's also new and fast. Let us know what it's like!
Bristol TN is again in a shopping center. It's closer to the food places but you could walk to other shopping if you're there a long time. It's old and slow.
Bristol VA is new and I don't think I've been to it.
Atkins I have no memory of.
Wytheville is hidden behind a hotel. It's old and slow but if you want secluded it's good? There's no good food nearby.
Salem is at a Sheetz gas station. Get used to it - it's common out that direction!
Now we're getting into territory where my memory is sketchy ...
Lexington has two. The newer one appears to be far superior of a location and obviously faster. The older one does have a couple restaurants. It's hidden behind hotels too though.
Raphine - new never been there.
Staunton. Old. At a Sheetz. I think I played catch football with a stranger there.
Harrisonburg, Sheetz again. As I recall there have been profoundly bad drivers entering and exiting the gas station every time I've been there.
Mt Jackson, old Sheetz. Nothing else around.
Woodstock, never been. Looks way better.
Strasburg, old. My personal map says I've been there but I don't really remember it.
Winchester new but at a Sheetz again. Bleck.
Frederick I haven't been to either.
Man that trip is probably so much better now! I should make another trip to the Annapolis boat show
