I don't know that I much like the idea of having to throw away a several hundred phone just because the battery went dead instead of just replacing the battery. Manufacturers must love this. Although I don't know what the expected battery life is of phones these days.
That depends on how often you charge it and how much you abuse it.
Without taking special measures (just sticking the phone on charge overnight) my phones generally last 4-5 years before the battery life becomes really problematic. I suspect that these "100W fast charging" schemes which the bloggers and marketing types seem to think are a good thing would reduce that.
Of course you can replace the battery in these phones, but it requires taking the phone apart. Some are easier for that than others (you can find information on this for many models from the iFixit website). Or you can pay someone to do it.
The manufacturers have decided that this is what people want, and "the market" doesn't offer an alternative because they all do it. Maybe if enough people had just refused to buy sealed phones it wouldn't have gone this way, but as they all did it at around the same time really the customer wasn't given much choice. That ship has long sailed.
I don't use the vast majority of junk that comes bundled in the software. It is also annoying that these items can't even be removed. If I need software I can always install it.
Actually removing it wouldn't help as much as you think: since the pre-installed stuff lives in a different partition (which is why you can't remove it) you wouldn't get the space back even if you did remove it (I used to root my phones and do just this, so I know from experience that this is true).
The annoyance is when they don't let you disable it - in principle they are only supposed to do that for stuff that's genuinely essential (to stop people breaking their phones by disabling things that actually are important), but I've seen major manufacturers, never mind carriers, protect pure junk that they've been paid to pre-install from being disabled.
If the phone length is 6.25 in or less than I would expect the width not to be an issue - nor the depth.
You are more tolerant of wide phones than I am then
I rarely use the cameras. I had to take photos for storm damage for the insurance company once, and on occasion I have to send a photo of a driver's license or some such somewhere. Plus, on occasion, there are the obligatory marathon related photos.
I use it mainly for music while running, Facebook, messaging, email, tracking some crypto prices, banking deposits, cash sending apps, notes, various running related apps, google directions, etc. No games. Nothing exciting.
And as I've mentioned before, I need external SD card access.
I know. Kind of boring.
So Pixels, OnePlus, the Galaxy s21 series are out because they don't have microSD cards at all.
But for your needs you don't actually require a high-priced flagship anyway. A midranger with a large battery will do fine - I say "large battery" because if you don't have to charge it so often I'd expect the battery to last longer. The only downside to that strategy is that you probably won't get software support for as long (this is why I stop at "midrange", because the cheaper devices will rarely have a decent software support period).
So my first thought along those lines was a Samsung M series (reasonable specs, inexpensive, very large batteries). But if you get annoyed by junk apps Samsung are far from the most streamlined (though LG are also prone to non-minimal software loads). The Samsung XCover Pro ("tough" phone) even has a removable battery (there are still a few that do, though not many). Moto do a few possibles, and add less stuff to their ROMs, but their software support will be shorter. The only LGs I could find released in the last year that met your size spec and had microSD slots were very low-end, which probably isn't what you want if you want the phone to last a few years.
But really I recommend having a play with that search tool I linked and see for yourself what exists. As it will only show 70 results you may need to narrow things further (by brand if you can't think of any spec that would matter). Your constraints are at least less out of step with the market than mine (I'm not interested in any phone > 7cm wide, while the market is now mostly things of the size we used to call "phablets", so my options are very limited indeed).
