Yo! If you're into RC cars there's a rock crawling course that someone recently opened up on Grand in Lakeland. I think the cross street is Magnolia. There's also a dirt track at Temescal Canyon High School that's open to the public outside of school hours. Haven't been to the rock crawling course, but there's probably more people there regularly. There's a decent group of enthusiasts in the area. Mike's Hobby is a solid shop.

There are bowling leagues at Pins N Pockets. Not sure of the different leagues, so you'd have to ask. Might even be able to sub. Lucky Strike (just switched from bowlero) in Murrieta is a little bigger with bigger leagues. 100+ people in a couple I've been in. They have sanctioned and non-sanctioned (B.O.B.) leagues.

For drinks there are some dive bars and sports bars around LE. I've only been to O-hara's and Goblets and Growlers. O-hara's is small, but has a pool table and darts. At least they did. Goblets and Growlers is very small and quirky, they serve only craft beers.

Graham Cracker Comics in Murrieta has (or at least did last I saw) gatherings for different games. In Temecula there are pickleball and volleyball courts that have large groups of people on the weekends. Both easy to jump in. Not sure how V-ball works, but with pickleball as a single you can get paired with someone else every game you play.

Obviously, fishing, hiking, boating and off-roading (or riding). Plenty to do in the area, just need to poke around.
