Not new to bitcoin but very new to living on a bitcoin standard. So, as usual, do the work and make your own decision. I think Strike and Fold are the best options. Looked into Bitrefill and similar options but not a big fan of buying gift cards (personal preference). I wanted to use Strike now that they have a lot better functionality than at the beginning. However, I had a bad experience with their KYC/support; twice (again, personal preference). I settled on Fold. Been working great so far. Keep in mind I'm only 30 days into this.
The one issue that keeps me up at night is BTC volatility. From a hodling perspective, I could care less. But converting pay into 100% btc regularly could pose a problem during a drawdown. I guess it's like an ad hoc DCA strategy? We'll see. You mentioned a small account to start with which is probably a good idea anyway.
