Yes we need better pictures of some of the larger ones confined in a small amount of water in a plastic zip snack bag. From the initial pics and video my best guess is they are larger young of year(YOY) shiners, however no money on that bet. For sure the smaller 3/8"-1/2" ones are minnow/shiner. In the video,, I think the fish swim more like young shiners than yellow perch.
When did you see and what dates for the YP eggs this spring??? Are you feeding the small fish crushed pellets? You can add food around and in a small mesh net,,,,, be patient, and lift the net when fish are in it. The bigger the net the better this will work. I doubt that you have a 1/8" mesh minnow trap which you should have if you are regularly wanting to know who 1" minnows are? They make 1/8" mesh drop nets that when baited work pretty good for catching small fish. I have bought special custom made 1/16" mesh drop/umbrella drop nets from Douglas Nets; tell them BillCody referred you to them. You will get good service from them.

They look like minnows to me. Swim/school like half grown minnows. I've got shinners and perch but they haven't spawned yet...new pond.
I get minnow fry "blooms" where there are football sized clouds of them all along the shoreline, this time of year I have the clouds and out in deeper water minnows from grain of rice size to 3/4 of an inch...bazillions of them. When I feed it's a free for all...my perch dart right up and back down to get at the feed (although I would think they would be stuffed full of little minnows).
Welcome to another MI pond owner!! Exciting to hear about ponds in the 'true north!'
I doubt gams are there since they would not overwinter in a northern MI pond
Their body shape in the still pictures look like 'shiner' but that is a broad category still. If the only shiners in there are ones you put in then you would know already what kind they are (GSH) Trap some and put in a white dish or in a clear bag with water and get better pictures. I see only positives to having clouds of shiners except for the issue of balance where too many shiners can inhibit recruitment of YP as they eat all the swim up fry before they get a chance to grow up. You have LMB to help keep the GSH in balance though.
YP young are that size by May and much bigger by August. It would be interesting if you can join us each spring when we all post when we see YP minnows and figure out what day of the year, what your water temps are, and whether they lay eggs on certain structure or bottom substrate as a preferred egg strand laying area. also if the S or SW corner of your pond is where the strands are laid first. The 2022 YP egg watch thread will likely pop up somewhere around March 10 or so and first egg strands forum wide I think are around March 12?
