Question Would like some help understanding the relationship with fps and upscaling with FSR.

My moniter(tv) has a maximum refresh of 60hz @ 4k, and 120hz @ 1080p. At native resolution, I can get 60fps with 99% around 50 with my xtx7900. Without modifying my fan curve I get pretty warm.
My main questions are if I set my native resolution to 1080 120hz and upscale it to 4k, would it be 120fps max or still 60?
Next, since my max refresh rate at 1080p is 120hz, if I do this, would it use less than 99% of my gpu since I'm throttling the fps @120? Would it keeps temperatures lower since I'm not pushing my GPU?
Lastly, would any of this help my 1% lows?
I'm not having any problems, but am curious and would like knowledge.

Unless you're using V-Sync or framer rate limiter in the driver or games, your hardware is going to push as many frames as it can (i.e., there's no maximum frame rate)

Next, since my max refresh rate at 1080p is 120hz, if I do this, would it use less than 99% of my gpu since I'm throttling the fps @120?
Yes and no. The percentage you see is simply the inverse of the video card not idling. 99% means the video card had something to do 99% of the time.

This can become skewed based on clock speed. For instance, if your video card was running at 2.0GHz with a utilization of 50%, it could drop down to 1.5GHz, still get the same performance, but utilization went up to 66%.

Would it keeps temperatures lower since I'm not pushing my GPU?
Yes.

That depends mostly on the CPU or how much stuff is going on visually.

If the main issue here is the temperature and you don't want to change the fan speed (is this a noise issue or you simply don't know how?), the other option is to drop the voltage. AMD CPUs and GPUs are always set too high in their voltage, this causes them to run hotter than they need to. Even a 5% reduction in voltage can make a huge difference in temperature.

It's more about efficiency than anything else. I haven't messed with the voltages or any of that because I'm afraid of voiding my warrenty. The CPU gets into the mid 80s and the GPU into the lower 90s when gaming for long periods or doing rendering. If I ramp up the GPU fans to about 70% constant, temps for both fall and stay in the mid to upper 70s. With a game like Starfield, it's expected for things to get warm, but I wouldn't expect games like gta5 or Skyrim to run as warm as they do.
I figure I should just not be lazy and make gaming profiles for individual games so I'm not just dumping pointless frames. And undervolt a bit.

Unless you have v-sync on (or set a limit), then in those less demanding games it will still work hard pumping out more frames than you need...I've always found v-sync feels more fluid than just running crazy high fps, but some might disagree.

Anyway, I have a 7900xt, in Adrenalin I set the voltage to 95% and saw quite a reduction in temperature while performance actually seemed to increase slightly...I haven't bothered pushing the limits of what it can do, this works fine for me. Also, if you have a Ryzen CPU, you want to curve optimize to reduce power consumption and heat....on my 7600x I used "Ryzen master" to curve optimize and then save the settings to bios.
