Until you know what you're on about with electric at an extended hands on personal level, and there's no way to gain that understanding without that experience over time, my advice would be to buy something versatile, reliable, reasonable quality which is moderately priced. At present you're wanting a Utopian single tool which will do every job. That doesn't exist in the guitar world any more than it does in the tool world, other than a compromise at most. e.g. the shifting spanner & a hammer.

IMPE high profile brand name guitars within any segment spectrum aren't better, just more expensive. When you do come to change over when you know the direction you want to go much better, the depreciative loss on a modestly priced unit described will be insignificant. But hey, its your money.

Style. For a jack of all trades, IMV&PE a Strat style guitar fitted out HSS where at least the humbucker is alnico V is arguably going to offer maximum versatility and minimum inherent design tuning issues. Inline tuners string routing off the nut, 6 saddle intonation, and the bridge can effectively be 'locked down' if preferred. Most have coil split humbucker functionality implemented today. Good range of available tones with 5 way selectable switch config. Weight and balance of the design is generally good too.

I've got a few styles. My personal preference is for modern invocations of original designs taking the best of the old integrated with the much improved upon new.

I've owned or currently own & play:

SG traditional

LP Custom style

Strat style x4

Tele style x1

Tele x1

My favourite overall is the contemporary mod Tele style. My least favourite the LP style, which although my Custom is still a solid mahogany body but with a faster friendlier neck, has the weight of an anchor and characteristically balance about as poor as that of a Gee Bee racer from the 1930s, but is still lighter than a LP traditional!

Most versatile by far, and well liked by me is the modern implementation Strat style of which I have three HSS and one a P90 + H fixed bridge config.

Personally, I just don't like vintage or even current Fender Strat necks, much preferring modern C or D and larger radius implementation in many similarly styled offerings. My advice is to try the necks first if you can. Don't just buy on brand chic or virtue signalling kudos alone. There is plenty of choice.

Heartily endorse Boss' Katana 50 as a decent all rounder amp choice. I own four amps currently, but don't own one BTW. They are darling of the moment, so as is the wont of Boss, come at a price premium for that versus the competition, but are still worth it IMV that as a solid safe choice within that segment. You can be pretty well assured it won't disappoint.

Cheers. Happy hunting! 🤔😀
