After a hardware upgrade I ended up with a spare mini pc. Noticed these two icons and thought I might be able to use it as a WiFi access point with VLANs using OPNsense.

Is that possible? If so, what do I even need to buy to plug into there?

I don't need it to do any fancy dhcp, dns or firewall stuff, I just need a WiFi access point with support for VLANs.

I've done this before on Ubuntu. You can install nftables for routing, then install hostapd for a wifi AP.

Sounds like a pain to configure compared to some of the more designated systems. Is the advantage that you use Ubuntu for other things as well, so it's a more multifunctional system?

That's basically it. My Ubuntu server is a router, NAS, plex server, public statum-1 NTP server, wordpress server, nextcloud server, security camera NVR, SMTP/IMAP mail server, CUPS print server, tor relay, and probably a few other things I forgot about.

You can do a lot with a single CPU from 2015.

I don't have hostapd on it anymore. I now have dedicated APs on OpenWRT. The main problem with using a WNIC for an AP is that they don't typically have a very strong broadcast output. I had to add an amplifier, and even then it wasn't great.
