If the gym has active fighters with decent records, goes to grappling tournaments, has active sparring, has a few blue or purple BJJ belts, people have cauli ear, you've probably found a decent gym
If they have losing records, the coach looks like hes never fought, has no record, or starts talking about death strikes you've got a meme gym

depends, do you have any background in combat sports?
joining a BJJ gym which does both gi and no-gi would be the best place to start, since along with BJJ groundwork you'll also learn a bit of standup wrestling (all BJJ matches start as wrestling matches on the feet).
from there take you pick of boxing and/or muay thai for striking. if you're a big boi (200+ lbs) definitely focus on the boxing.
from there you'll have the base to start actual MMA, which is just kind of putting it all together. I would recommend competing in one of the specialties first though, especially if you have never competed in anything before (i.e. do a wrestling or BJJ tourney, or have a low-key boxing/muay thai fight)

Unless you plan to compete and really take it seriously, there is no point in hard sparring. All you will get is accumulated brain trauma, and a laundry list of concussions along with the way. Stick to light sparring and technique - and spend your competitive energy grappling (bjj, judo, wrestling).
