• If you pay for privacy oriented online services, mostly by providing a privacy respecting service, they often accept Monero.

    Off the top of my had I know that Mullvad VPN and Standard Notes accept Monero, but if you look for it, there are probably more.
    Other than that, PrivacyGuides recommends CoinCards as a gift card store that accept Monero payments. CC has gift cards for several popular online services. They are not yet available in Europe, but if you know that the service you want to sign up for does not enforce using the gift card in the appropriate region, you can buy it from a region that is already supported.
