Is this the case for all Model 3's or does the LFP battery only come for the SR+MIC models?

LFP battery, charge to 100% each night?

No thats not true in the LFP chemistry... the biggest problem is there are too many opinions online and not enough fact!
The charging regime you talk of refers to LNM chemistry batteries the new Made in China Model3s with LFP no longer have the daily charge set points as charging to 100% once per week is recommended.
That’s pretty much what the Tesla Rep told me in Bristol. So that’s what I’ll be trying very soon
I have a MIC SR+ which was delivered yesterday. It came with almost no juice so I charged it to 100% overnight. There is no upper limit.
Regen this morning was exactly the same as regen yesterday at 9%. State of charge therefore makes no difference.
What might make a difference however is the battery temp. It's currently very warm here and I had scheduled departure for 6am which I assume also does battery pre-conditioning. I'll disable scheduled departure for tomorrow and feedback as to the regen experience.

I have seen some discussion that the LFP battery may have a 'hidden' buffer meaning that 100% charges are not absolutely filling the battery and also that there is still some capacity to use regen at a quoted 100% level.
I’ve taken delivery of my MIC SR+ 2 a few weeks ago. A 100% charge with a stone cold battery, no regenerative brakes. 100% charge and using the climate function with battery heater, regen brakes works straight from the driveway.
While charging, I looked at the Set Limit options for the battery and I found that there is a 90% marker for the battery now.
I think there was only 50% and 100% before?
wonder if this is a new suggestion that LFP does benefit more from charging to 90% compared to 100%?
Car is a 2021 Model 3 SR+ MiC 2021.24.4

Reckon the 100% recommendation still stands then ?
Thought they might have had a 90% marker for some reason.
Sorry I misunderstood what you meant, I was referring to the 10% increments (50-100) but I just went and and shifted my limit and recognize what you were saying where it stops at 90%. That too has always been there on mine, in fact it was that and how the line is presented differently at 90 and 100% why I emailed Tesla asking about 100% charge. They did respond (I have a 50% success rate so far with responses
) recommending 100% charge once a week.

Yes - I'm actually quite ambivalent on whether I charge to 90%, 80% or 100%.
Of course the pedant in me wants to see 100% daily, but I just want whats best for the car in the long term.
I’m not working much at the moment due to covid, so I leave mine at 55%. This would get me to work and back with a few % of ‘fumes’ remaining 
is why. The consensus for storage says around 50% but that was for NCA, I’ve not read much in this front for LFP so who knows if I’m doing good or bad? For daily use when I actually work, I charge to 90%. This allows me a work commute, plus any other things should I take a detour.
There is an absolute stack of Info/opinions out there, this thread Should LFP batteries be charged to 100%?
has some interesting info from mpandrew on the first page.

I suppose if LFP is really all that it's cracked up to be, it won't matter too much either way.

TeslaFi solves that problem, it's easy to type in an exact percentage.
FWIW, there's no point charging to 100%, if it's a true 100%, as you'll lose regen, as others have said - which is an inconvenience, rather than a benefit.
