Issues with various apps talking to servers (Steam, Discord, Paradox)

I'll be the first to admit that I am not particularly familiar with networking.
I am currently experiencing an assortment of issues with apps but they do not occur in Firefox. Steam works fine in browser, but I want to play games that use the steam friends network to handle multiplayer. Discord works fine in browser as well, but the application tries and fails to connect to servers to check for updates and otherwise connect to servers at all. I play Stellaris a lot, and if I launch it directly, the Paradox Launcher is unable to connect to its servers to let me log in. All of these things work just fine in Firefox, but outside of Firefox they seem to have an issue.

Things Ive Tried:
Steam: Steam beta client, steam native runtime, ensuring I have the 32-bit dependencies installed as is indicated on the wiki page for steam troubleshooting, cache clearing for web browser and download in steam, clean install of steam, reboots
Discord: Multiple clean installs of discord, discord-canary, and discord-dev. Same sort of issues with not being able to reach servers.
Paradox Launcher: Can launch this directly from the desktop icon or by searching for it, but it's useless as Paradox can't connect to it's servers to log me in nor can it connect to the steam Friend Network. Tried clean installing stellaris

I believe this may be some sort of DNS issue based on some other old reddit posts and forum posts I've found from a few years ago, but haven't had any luck. I've tried enabling nscd.service and restarting. I've tried enabling systemd-resolved and restarting. Nothing seems to work and I'm at a loss. I don't really understand DNS beyond the very top level.

My system is up to date and otherwise free of issues.

Here is my /etc/hosts

# Static table lookup for hostnames.
# See hosts(5) for details.
127.0.0.1      localhost
::1            localhost
127.0.1.1      noaharchgaminglaptop.localdomain noaharchgaminglaptop

You can try replacing the contents of /etc/hosts with this:

127.0.0.1      localhost
127.0.1.1      noaharchgaminglaptop.localdomain noaharchgaminglaptop
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

I was having connectivity issues with Uplay (Ubisoft Connect) and this helped.

Unfortunately this did not solve the problem even after a reboot sad
I think I'm gonna just have to clean install at this point...

Bullshit. Also you'll likely just end up in the same situation again.

The DNS estimation is sound, FF will likely use its internal resolution mechanism.

So let's see. Outputs of

ip a; ip r
ping -c1 8.8.8.8 google.com
ping -c1 google.com
drill  @8.8.8.8 google.com
drill google.com
nslookup google.com
stat /etc/resolv.conf
cat /etc/resolv.conf
cat /etc/nsswitch.conf
find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f
