Lower assembly looks good to me.
The anderson rollmark is a little cheesy, but the ones I have are in spec and were cheap ($60 each OTD from local ffl).
I see both those uppers you listed are now OOS. You gotta jump on those daily/weekend deals real quick.
My first few uppers assemblies were PSA. Back then, they all came with BCGs and CHs and there weren't different quality levels (Premium, PSA, Freedom, PTAC). All barrels were FN and CHF, even the stainless ones. If buying something today from PSA, I'd want the CHF and chrome lining too.
As long as you stay away from the PTAC line, I think you'll be happy with whichever PSA item you end up with.
If you don't already have the tools or know someone that does, you're probably right that you won't be replacing the handguard/A2 front sight with a FF rail. Buy the configuration you want.
Good BCG choice. Never tried a Mod 4 but somehow I have a Mod 3 amongst the CHs I've got. Raptor replacements are almost complete for my stable.
You seem to have a good idea of what you are looking for, next time PSA is running a deal on something that catches your eye, flip a coin instead of coming here for advise and you won't miss the deal.
Good luck.
