FIRST and most of its teams are very open to collaborating and supporting rookies new to the org. I recommend reaching out to as many nearby teams as possible and see what support they can provide. Any serious teams are motivated to help as this directly contributes to their team's success during the competitive season. Competitions require a teams to have a pro-social aspect to their operations. Helping other teams is a strong signal in this area.

Additionally, find a nearby FRC competition and volunteer for at least one event (do more, if you can). Wander the robot pit and interact with the teams. There will be a lot of good intel for you there just wandering around and asking questions.
