You’ve received some excellent recommendations, and I think @bobmac has given you a great idea for how to talk with people. Since you’re new to racing, I highly recommend the Early Birds. Even if you’re not planning to do a lot of crits, the EBs are GREAT for learning how to race safely. Here’s the flyer:

The clinics and practice races are both FANTASTIC. Try to go to all four weeks, but if you can’t make it to all four in January, they’re apparently extending them through February this year. I haven’t seen all of the details for the extension, but it’s nice because you get another chance to attend the clinics this same year, rather than having to wait until next January. Plus, you get upgrade points for the clinics and practice crits. You also can meet different teams at the EBs and talk with people from different clubs–in fact, there’s a “meet the teams” day!
Also, FWIW, I suggest prioritizing “getting along with team members” and “convenience”, as well as the suggestion from someone that you pick a team that has racers with similar interests as you. Particularly as a new racer, I would not prioritize sponsors or historical team performance. Sponsors are nice but not vital to your learning or performance; historical team performance doesn’t mean that they’ll be great again this year. Good luck, and see you out there!!
