How to get started with Bitcoin payments?

There's many peer-to-peer payment apps these days: Venmo, PayPal, Zelle, Google Pay, etc., and those are fine for most payments, but in some situations it's valuable to have the ability to make anonymous payments, and the platforms I mentioned are not great for this.

Because of that, I'm looking to get into Bitcoin payments. Is that the right idea? Is there a good (reliable and trustworthy) platform that makes it easy to transfer money in and out? Ideally with a nice website, and maybe an Android app. Thanks!
