It really depends on you, there are more resources than ever to help from text, YouTube videos and of course paid courses. Start small, see what you like, Tech is a marathon for most. Can a NET+ help fill in gaps, sure but so can trial and error on your own hone lab. If you are just going for knowledge and not to further a career just stick to the free stuff.

It's entirely up to you. I did have a bunch of such certs, but none of them were actually useful for real-world setups; the knowledge I used for self-hosting came from me mucking around on the internet and reading RFCs and instruction manuals.
Thanks for asking the question. I am in the same boat. I am decent with the hardware and container stuff. Then I get totally lost the second reverse proxies, tunnels, and firewalls come up. I have been stumbling my way through most of the network stuff but I think some basic networking knowledge might help me also. I am Interested to see if anyone links some good courses, YT channels, or videos.
