Well I cant say specifically to your setup. But I have an old server that I use as a hypervisor running Proxmox. On it I have an OPNsense VM Ive been running for years now. I dont do any crazy pass thru stuff. I just added each NIC as a normal network device bridged to the specific hardware port. I also use it as a Reverse Proxy for all my internal service such as Emby.

When Nova sold out I moved too. Hyperion https://play.google.com/store/apps/details?id=projekt.launcher Well as far as I know its not open source. But I did find it to be a decent Nova replacement.

HP VARs were calling me and wanting to do business and they do. (Not Printers, servers and that kind of stuff.)
I keep telling them I wont even look at their stuff due to HP anti consumer practices.

Desktop: Google done fucked up. I didnt use FF cause of one of my extensions but I opted out when they started talking about the DRM for webpages.
Mobile: Its just better with Adblock.

Personally I do both. My VPS takes care of stuff like DNS, Email, Webhosting, and a couple of light services such as Syncplay.
I use the Control Panel called ISPconfig for DNS email webhosting and etc.

Then I have Proxmox at home behind a reverse proxy for services such as Emby, Game servers, NAS, Mumble DJ Bot.
