Restrooms on Amtrak don't make you deaf. No stupid food carts blocking the way to the restroom. Even on parts of the world that have food service on trains, the carts don't block people from walking past them.
You can walk the entire length of the train whenever you feel like for exercise.
Turbulence is not a thing on trains, and there's much more space to get from the window seat to the aisle without needing to crawl over a stranger's lap.
Also, there's scenery almost the whole way.
It's unfortunate you can't seem to make too many stops along the way. The company will allow for one, I believe, but as you try to add more the tickets get more expensive. The timing of arrival and the small-town location of many of them just make the option not very interesting for general tourism. I did have a few hours in Chicago which was pretty cool, though I didn't see much and was very put off by the "if you're being shot at then throw your duffel bag at the attacker" videos at the main station. But it was also the middle of winter and like 7-9am or so, so that definitely coloured my experience. Great diner experience though. No one does breakfast quite like North Americans.
Talking with a nice man from California in the restaurant car when I did go the one time I learned he paid as much as me for one of the private room options, just he'd booked a few weeks in advance. I believe he also had access to a shower, which would have been a game changer for me. I booked the way I did though primarily to test out the "worst" option and compare it to better options as I'd make more trips. This was what I learned so far. I'd like to do more though, because this seems like a great way to travel the country.
(You can get a room with a window, but for an overnight trip it seemed a bit pointless.)
I find it difficult to sleep on sleeper trains, and usually arrive tired at the destination. Where there is the option I will use a night train out of principle (it's still usually more comfortable than a plane) but, if I have time, a daytime rail journey is much nicer.
And Aeroflot are not known for their hospitality and understanding to foreign travelers...
Any particular you know that in fact do cancel noise and really work?
On the other hand, a $400 set of Sony's will basically put you in audio isolation - to the point that some people genuinely don't like them. A friend had me put his pair on in the middle of a busy restaurant at lunch time and I'm not kidding when I say it felt pin drop quiet.
My Airpods Pro are great but they only have a battery life of 4-5 hours per charge (20 hours in case, but you have to wake up to charge them).
My Bose QC 15 over ear headphones can stay on much longer (> 20 hours of battery life) and have great noise cancellation, but as soon as I lean my head to either of the side headrests on the seat, the noise cancellation "leaks". I've never been able to sleep on a plane with my Bose QCs.
The best solution I've found so far have been plain-old ear plugs ($5).
Since they're cabled to an external battery box they can easily last through any flight, and you can leave the USB charge cable connected to an in-flight power socket while you use them to keep the battery full.
Eye mask, you want the kind that looks like a bra and puts no pressure on your eyes. "Nidra" is the brand I usually get, they're cheap, I replace mine regularly.
Noise canceling headphones. I go for cheap sets but get what works for you, something wireless. I have found history podcasts and music both work well for me.
I have a neck pillow that basically looks like a cervical collar and is made from memory foam. Works really well for me but was pretty expensive, and it takes up a bunch of space so it's a tradeoff to consider. And wear a zipped sweatshirt on the plane, use it as a blanket - after turning the air vent on max.
