My opinion

Three chords— C. F. G7.
The action, tone may be less than optimum, but like a cheap piano, you can ‘see’ if you enjoy plunking around. Hundreds of songs from various categories can be played with three simple, easy to learn, easy to play, chords.
Then, head to a good music store and figure out what you want in terms of size, sound, strings, etc.
Do you like warm sounds, bright sounds, sustained or quickly dampen. A lot to consider, which is where UAS comes into play
My Banjolele, eight string, low G low C low E low A, acoustic/electric cutaway tenor....
All play different and sound different.
Good luck.
