I've use BTC to pay for VPS services and also VPN few times before and if you are looking for more you should get bit refill app on your phone, you can buy many things through this app, from gift cards to airtimes and even pay your bills like electricity bills and other.
I've also use this app to get eSIM, they Algeria, Australia and also Global too, they have access to cool hotel offers, like bonus offers, I don't think anything matches the level of this app, they accept BTC, USDT, and some other altcoins too.
Most VPN services now have crypto payment options and I believe in time many other services will start accepting Bitcoin and others too, it's a slow but steady journey, we will get there some day.
That is actually making some sense, if you want to use VPN that means you want to hide where you go from your ISP and that means if you like to pay with crypto that would be another way of hiding it as well instead of giving your full credit card information which has your name on it.
This type of stuff makes sense, this is why I always suggest that crypto is great for online payments, because you can hide who you are, and I do not mean online like you buy something for your house, that will be shipped and need your name, I mean digital stuff, even including ebooks. That way you get something digitally, a product or a service, and do not have to share your personal information at all while buying it.
