Which kind of hardware (used computer/single-board computer/dedicated server machine/NAS/something else) and operating system do you recommend for a home server like this?

Proxmox has been pretty good to me. I have an ancient office PC that has proxmox installed as the hypervisor. It's based on debian but everything is done via a web interface (you can ssh or whatever into it too if you needed to). Then I have debian with docker containers, TrueNAS, and home assistant all installed as VMs. Benefits to this means you can put mission critical stuff on the "boring" debian and then have fun with whatever you want to tinker with on an entirely different os/Virtual Machine. I also use wireguard easy which is stupid simple to setup a VPN with. I would strongly recommend keeping all management of the server on the local network and use a VPN to connect. This will get you the "enterprise grade" security. Anything public should go through a reverse proxy/DMZ VM if you host something on the Internet. Use cloudflare or similar as an extra layer if you need a domain name and want a buffer between users and your network. Keep that device and software up to date and you should have a great defense.
IDS wise, it's a lot of work. You're better off spending that time working on building security by design by doing the above and ensuring anything that touches the public Internet has as little permissions as possible (no running the web server as root/user account), firewall management, etc. If you do want the challenge, or are Interested in learning something like security onion, wazuah or whatnot, don't let it stop you.
Hardware wise, affordable and uptime could mean it might be cheaper to have a backup machine. Proxmox has features to support high availability where if one of your physical servers go down, another can take over (2 physical servers that are copies of each other). You could have a decent workstation and then a used PC or whatnot as the backup. More important is probably a UPS and some workstation gear unless you want a screaming server jet in whatever room it goes in. Nothing you've mentioned seems too performance heavy so technical PC recommendations are going to vary based on expected traffic or use cases. My 2014 DDR3 office PC manages just fine but it's for very few people and in air conditioned space. You could probably price out mid grade consumer equipment for the main server and a used office PC for redundancy.
