Maybe a dumb question, but what are the advantages of such products compared to just configuring a "plain" wireguard server i.e. on OpenBSD? I'm not a network expert and still it was pretty simple. Do these products offer more features? What kind of features?

Try to build a mesh with wireguard.

You will soon find you have a combinatorial problem. If you have 10 nodes and want to add an 11th node, you will have to update the 10 already existing nodes.

These projects are automating the configuration of the nodes. You simply configure a new node and the other nodes are informed of the presence of the new guy.

I’ve built a 3 node wireguard mesh network, by hand, and it did get tedious!

tl;dr: you don't have to configure wireguard yourself and it can help you meet acronym compliance

this would be the big one for me. I'd be more likely to trust their configuration (security wise) than my own.
