I think you can easily get started by using https://lightningnetwork.plus/. I understand most "larger" nodes won't want to join a swap with tiny ones, but in my experience, it works as leveling up in a game. First you need to join swaps with other tiny nodes (<10M sats, <10 channels) and when you grow in size, you end up joining the small nodes club (10-50M sats, 10-30 channels). After that, you go a level up and so on and so forth. It takes a bit of time and patience, but it can be done.

If you post a link to a 1M sats triangle swap in LN+, I'll be happy to join it.
