In my (limited) experience, being on break when your team plays probably isn't an option (what if they make the playoffs?)

Only you can answer the question of whether you're comfortable refereeing when your team is on the field. This includes not letting your biases affect anything (in either direction!), not being able to give any advice or help to your team while on referee duty, and being stuck out on the field if there are any problems or issues. If you truly think you can handle it, feel free to volunteer, just be upfront with your potential conflict of interests.

I refereed an event last year with my former team, which I still feel pretty close to, in attendance. I refereed some sporting events at college with friends involved, so it wasn't a huge deal for me - although I did make one call that tilted a game in their favor (I made 100% sure it was correct...)
