Recently I discovered Nostr, which is a distributed Twitter alternative less centralized than Mastodon, and there are paid relays you can purchase access to with Monero.
I personaly donate to some Russian media outlets with XMR, which is not exactly a service purchase, but a good way to help them to survive government pressure.
Monero does not appreciate in its price as much as mainstream cryptocurrencies so I am not holding much Monero. Rather using it occasionally to buy the hosting/server services for privacy. I can buy/sell XMR privately for fiat or BTC/ETH/LTC using RetoSwap https://github.com/retoaccess1/haveno-reto
