Could be the A/C clutch engaging. If its only during the remote start cycle, the Hvac system kicks on the a/c to defrost the windshield.

I really appreciate it man. I’ll definitely check into the belt and idlers. I got home and was able to catch the harsh start up I was talking about earlier. Not sure if everyone’s does this if it sits for a little bit or not…Bro, we want to help, we are Raptor enthusiasts, I mean there are some trolls on here, but 99% of us want to see owners enjoy their Raptors and get them in the right direction. You will need a socket and a prybar (long ratchet) to move the adjuster pulley and then the belt will slip off easy, same as putting it back on, maybe have a friend help you or it wouldn't cost much to take it to a local shop and have them give you a quote, some might do it for free! (maybe not).
Here's a little write up on what you might be experiencing :
Ford F150 & F250 How to Replace Idler and Tension Pulleys
Squeaky belts and pulleys are the bane of any person who has to deal with them. Swapping out those noisy pulleys and belts its actually a...www.ford-trucks.com
Your video didn’t sound like mine, but I recently replaced the tensioner and idlers on mine. I have like 57,000 and some change on it, though it lives an interesting life of sitting, long highway stretches and then a few hours at about 4,000 rpm lol.
I just pulled the belt and spun the pulleys and it was easy to figure out which one was the problem child. I replaced both idlers and the tensioner. Motorcraft tensioner had a nylon pulley, I went with Litens (I think that is the brand) and they are supposedly the supplier for motorcraft and had a steel pulley.

I agree with MTF
Sounds normal to me from the last video you posted
Loud lifter noise on cold start is what plenty of 6.2s do

Yup, that last video doesn't sound bad to me.
I switch up to 5W 30 weight almost two years ago
and it does help with the valves tapping a few seconds at startup.
Especially when Supercharged.

I like the Nylon/Teflon pulley better than the steel one, the Nylon/Teflon is gentler on the belt.

I appreciate all the help guys! It’s making me feel a lot better, I thought I was gonna implode worrying about this truck so much.

Mine doesn’t make that lifter noise, but if you guys think that’s normal, I’m just glad mine doesn’t do it and mine will sit for a few days even outside on a cold day is quiet.

Mine will do that on occasion and has been doing it forever. I thought it was something about a hydraulic lifter valve train adjustment doohickey and if I remember correctly from 9 or so years ago when I first started hearing it was considered normal even though sometimes you are like WTH is that? Always goes away within a few seconds. I feel like when I do hear it, it’s more towards the back end of when my oil change is due, but I don’t know.

My understanding with the valvetrain ticking noise the first few seconds at startup is:
The cam phasers need oil pressure to unlock the pins and start operating, it's that simple!!!
