I’d think the answer is yes due to the lack of that type of radiation, but I haven’t noticed a significant difference in my experience.
(I did google, but I couldn’t find any answers to this)
You should look for semi-reflective or tinted glass if you want it to not let warmth pass in to your home. (And if you have double glasses, only the external one should be treated.)
The UV-blocking glasses will warm you less, but as you noticed, not enough to make a sensible difference. They add absorption of a very small band of light that isn’t the most intense on Sun-light and is also absorbed by the atmosphere.
No. The UV light is on the other side of the rainbow from the light that makes you feel warm: Infrared.
Infrared is the peak of the frequency range emitted by objects that are roughly body temperature—that doesn’t mean it’s the only frequency that makes objects warm.
In fact all light that isn’t perfectly transmitted or reflected makes things warmer.
Yeah I think my microwave has something it wants to say
Is it “mmmmmmmm”?

This is correct but also glass blocks both ends of the spectrum. Really just visible light goes through glass. You get some near IR passthrough but not much.
There’s glass that doesn’t block UV frequencies—like the glass used in tanning booths, UV lights, and UV cameras.
I would think it would depend on whether the material the light hits inside the window reflects UV light, or absorbs it and re-emits it as heat.
Even if it reemits heat, some will be lost to air via convection and half goes wrong way
Less than half, because glass isn’t a great heat conductor.
That’s true of any material that gets warmed by sunlight, though.
Slightly. Most of solar energy comes in as visible light, so any visible light that gets reflected won’t contribute
Not sure about how it feels on the skin, but here’s a good explanation of how Low-E glass coatings keep homes cooler in the summer

It definitely heats your DNA less!
