I mean, if you measure fps at the same resolution (every frame) that you're talking about, you will see the exact same variations. It really is the same metric.

Why are you mentioning DNS here?

if you're not already running some super low resolution, have you tried lowering your res to something like 1024x768 or even 800x600? super weak gpus, especially intel graphics, can actually see quite a performance benefit from lowering res in tf2, and higher overall framerate will make framerate inconsistencies less noticeable.

also, check your cpu/gpu temp and clockspeeds to make sure they are not thermal throttling, as that would absolutely lead to lower framerate and greater framerate inconsistency.

fps and average frametime refer to quite literally the exact same metric. diving (1) second by your frames per second will directly give you the average frametime over that second (eg. 1 second / 144 fps = 6.9 ms frametime).

what's the hitsound in beater's legacy videos?

seek professional help u sound like u could need it
if a video game is affecting you to that level then there's probably a deeper issue

Those are indeed areaportals, you can confirm with r_drawportals 1: https://i.imgur.com/ZteuijA.png

I'm not exactly sure why, but that seems to be caused by having mat_phong off. It only happens on a few props, like the harvest trucks and the mvm upgrade stations, but they look normal with phong enabled.

Wild (probably wrong) guess but do you have a custom font for chat in your hud? How would you describe the lag, is it your fps dropping somewhat, or the game freezing entirely for a bit, or something else?

They're basically just like constants that store a color and can be used in place of that color in all the other hud files. For instance,

"TFOrange"			"145 73 59 255"

in clientscheme.res sets TFOrange to represent the rgba color 145 73 59 255, and then you can write TFOrange in place of 145 73 59 255 in other hud files. This has the advantage of allowing you to change many elements of a certain color by just editing one file instead of editing a bunch of files.
