Buy European

The first I can think of (because I'm using them):

• Filen (E2E) encrypted cloud from Germany. Replaced my other cloud services for a few months now.
• Codeberg, for git stuff. I'm no dev (I just use it for my own little scripts) so I could not tell how feature-rich it is or if it lacks anything it is but so far it seems to be working great ;)
• Mullvad VPN, Swedish if I'm not mistaken.
• Should I also mention LibreOffice? It's not a European product, but its 'foundation' is German-based if I recall correctly.
• Hetzner a German company for cloud, webhosting and some other stuff I can't even begin to understand ;)

That said, I mostly focus on software being Free/Libre. Maybe in the coming years, with the rise shit nationalistic politics that we're witnessing, I will have to focus on EU-made products and services only—that would be sad.
