Lastly, repairing is again: optional.
If OP wants a phone to get over mandatory social topics where you can’t do without one, then how does it matter if they can repair:
- their mic
- replace a crack in the glass
- some crack on the camera
People live with shattered phone for months on because phones are quite sturdy when you think about it. They don’t look new and fancy, but they are still functional and can get you if you need a QR code, NFC or whatever the needs are for running some specific app.
Repair is not a silver and holly bullet.
This comes from a guy that sold a Macbook mostly because I didn’t wanted to deal with any potential issue with their screen ribbon borking it all the way.
Still, there are things where a custom made Linux desktop PC is just inferior hence I still bough a Mac Studio. Why? Because it is just more sturdy and less prone to dying because of static or random hardware problems.
Is it repairable? Not really. Does it matter, no because it is not on the move and very few things can happen to it.
Being pragmatic is important sometimes if you have a goal to achieve and don’t want to fight over a thing for 50 hours in troubleshooting/etc. Having an objectively better phone that does the job is better than being heavily political about your purchase.
Never said you said any of that, I’m just mentioning it myself.
Average Joe does not replace a battery, ever. They go and buy a new phone.
If you go with a Fairphone with that goal, you can probably figure out how to be careful enough and not shatter a Pixel because you’re a hobbyist in the first place.
Yes, bumping it slightly. What’s the point of going to 30% privacy bump rather than 99% with a Pixel?
You could say that you can improve any phone’s privacy with enough software, it’s mostly a matter of what you define “enough” while still being usable.
I consider that still having half of the tracking actively running on the phone, is just gaff-tapping an open wound while feeling accomplished of escaping Google’s claws.
I don’t know, you tell us what you need.
I assume from your question that you do care quite a bunch, hence I do suggest a “higher than meh” threshold and recommend a Pixel.
If you’re fine with a subpar solution, then you should probably not even change your current (working?) phone and stick with the gaff-tape approach, forget about Fair/Pixels.
How much hardware in your current house is non repairable (fridge, dishwasher, TV, heating system in the floor)?
Do you want to go and buy a repairable sub-par washing machine just because of politics? Do that enough and you’ll give up entirely.
At some point, you’ll realize that repairing all the stuff around and finding sub-par alternatives is equivalent to a fulltime job.
Depending on your age/responsibilities, you might have enough time. If you’re older, you’ll find out that it’s just not sustainable and that your time is more valuable focusing on other priorities while eating the bullet not DIY’ing your washing machine from scratch after learning about electricity + schematics of such a system.
The friction + needs should align in a realistic way.
Bending the knee to a lot of things in favor of the holly 100% repairability is not the way to go IMO.
It is cool if companies support and behave in that direction, yet you can’t say no to things that are closed-sourced/glued/unfixable because you need to live your life somehow on a daily basis.
Can achieve the same goal yes. 
[…skipping the snarky comment about the famous holly exploding glued batteries part
]
That’s the logical decision yes. But as you can see, this thread is getting quite political and about principles more than practical daily advice.
If you need a device for work primarly, security should indeed be far more important than anything else (like repairability).
Maybe you can also negotiate to have a dedicated device from your employer, if you have high OPsec/critical stuff that you don’t need to leak to the outside world.
