This is frankly a bit nonsensical. "In a workplace setting, connecting to your residential IP will raise suspicions or alarms." - so will connecting to literally any unexpected VPN endpoint if the network is halfway competently monitored.
Just because your VPN endpoint is on a VPS somewhere rather than a computer on your home network doesn't make it any more secure, and the scare mongering here that somehow a home router will drastically mess up a function as simple as forwarding traffic coming in on a port to another machine is weird... if you don't trust it to do that then I'd get rid of the thing because that's its entire job.
