Strat-style is peak guitar, IMO.
Chromatic scale is a fine starting point, too.
The frets are in good shape? The action is ok?
For chords, look up “The 3-chord trick” and you unlock a LOT of songs with that.
(I have no idea how much you know about stringed instruments, so apologies if anything comes across as condescending)























Explorer, SG or Les Paul?
