Run for office. Since it's hard to get up the gumption to run yourself (everyone here knows what imposter syndrome feels like), convince friends to run.
Don't limit yourself to Congressional races. Those are incredibly hard to win, especially for political outsiders. Run for parks commission, for library board, for school board, for town trusteeships, and for county offices. Run for water reclamation. You don't need to be a subject matter expert --- that's not expected of you. You just have to be willing to do a little extra work every month.
Any elected office gives you a greater voice in all of the rest of our politics. You use local offices to put pressure on your congresspeople and your state reps, and to build an organization to win more offices later.
This is what the Republicans have been doing since the 1980s, and as a result the GOP controls most US states.
Get a couple of friends together, and just pick one of you to go out for something, and then work as a team to collect information and plan outreach.
Even if you fail, treat the whole thing as an information gathering exercise. Take notes and share them. The GOP is crazy good at picking up local elected office, and they've had lots of practice. This is how they got that practice. Anyone who thinks local office doesn't matter should figure out who their State Senator is and how many constituents they have, and then look at Congressional redistricting --- it's state leg. that created the system in which rural Republican votes count so much more than urban Democratic votes do.
