The problem is not "Syncthing users" it is the others that we bring along with us.
I already have F-Droid on my phone, but the dozen others that I have promoted Syncthing to over the years do not. This is going to cause a bunch of problems.
This is much more important than what you portray here.
I needed to update my parents old NUC from Win7, it was either new hardware to run Win10 or give Linux a try, I told them I had been running Linux since 09 full time and it isn't any harder than running Windows.
I said how about you give it a go for a month or so and see how you go.
I installed Mint, it has been a few years now and no real issues beyond taking a while to get the printer working. I installed rust desk for remote assistance which I have only used 3 times since install.
That is one bold assumption right there.
KeePassXC + Keepass2Andriod, keep it all synced using Syncthing. Desktop/Laptop/Phone all have the passwords synchronized, it is super convenient.
I have been doing it this way for years, never had any issues; just starting to investigate using passkeys where I can. So that is a new adventure; I'll see how it goes with my current workflow.
I did email one site that had a message that it only worked with chrome, I said that switching my user agent fixed the "issue" and the site seemed to work with no issues on FF.
A few months later, no more warning.

Don't rush.
Base it on how you feel. If you still feel unhealthy, then sure, put on a few extra kg. But if you feel ok, then don't worry.

Earlier in the year I was in hospital for a while, had to have surgery. I went in at 80kg and after 5 weeks was just under 66kg.
I'm 175cm tall, BMI 26.1 (technically over weight, but was very fit) down to 21.6, which is considered "normal" but I felt very skinny and unhealthy.
The BMI thing is a little bit bullshit, since it doesn't map fitness level.
As for getting back to a healthy weight, take it slow, eat really healthy foods eat mostly nova 1 & 2 foods, some nova 3 and avoid nova 4 if possible.
Also if you have been on antibiotics while in hospital, eat ferments like kimchi or sauerkraut, maybe drink some kombucha to rebuild your gut flora. But take it slow as it can really mess you up if you dump too much in at once.

And in the end, you will come to love big brother.
This is one of the many things I use Syncthing for.
