I've only played one guitar in the past that didn't fit: a Martin acoustic (not mine and I have no idea what model but I know it comes fitted with an "aura" unit as standard); the spacing between the strings felt too wide.

Any electric guitars feel fine but not always the strings. I particularly dislike flat wound strings but that's a purely personal preference ( I've met lots of players who swear by them).

As for LPs, I've never owned one but I'd quite like to try a Studio model, because they're lighter, to see how it feels and sounds, then add one to the collection.
