I’m growing a solo SaaS in a tiny niche market. In the last six months I’ve gone from zero to about $200k ARR. My average subscription price is about $250/month.

I’m not sure it’d work for your price point, but I’m running Meta ads, and then having leads schedule a call with me (no public pricing). I close them on the call (they give me their CC to start a trial). That’s worked well, though I do want to move towards a self-serve model over time.
