Which of the starters is the best one besides Torchic? And which ones are inaccessible after the first choice?

So I've decided to replay Rejuvenation on 13.5.6 after two years, and I've figured out that most of the starters can be collected after the start of the game. As far as I'm aware, the only ones locked to that first choice are Torchic, Chimchar, Snivy, Scorbunny, and Grookey. Besides Torchic and Grookey, which one would be the best for a playthrough, and are there any other inaccessible starters I missed?

Cinderace and Blaziken are busted in singles, but Rillaboom is the most most meta of meta that ever was meta in VGC. The hardest battles, imho, tend to be battles, so, I'd go with Rillaboom.

Torchic, I think is the only starter so far that can't be obtainable outside of starter pick. The rest can be found either in the wild or as events. Even ones like Snivy are around they're just really late game. Scorbunny can be found after doing events so its only really Torchic that remains.

 

I'd spoil where the others are but I don't know how much you want them because they're pretty into the game.
