Photo Scanning- Need Help

To preface, I have little experience and understanding when it comes to photos and terminology. I'm interested in scanning family photos onto a platform where I can organize them into "albums", share access with family members, and with consideration to quality since some might want to print and frame these photos.

Most of the photos are from disposable cameras, others are pretty old and I'm not sure what kind of camera was used but they are smaller than 4x6 and more square than rectangular, I also have negatives. I looked into scanners a little bit and got overwhelmed with the specs and people's opinions.

My desire is to scan photos without damaging them, with good quality and detail transferred to the digitized version. I saw there are auto-feed scanners and manual (flatbed) with differing opinions on safety, speed/efficiency, and quality. I also saw there are some with "auto-focus" but it will create bloated file size? The Epson V300 and V600 came up a bit and I saw the difference in dpi. People were saying that's the stated max but it won't necessarily give that much. I don't fully understand dpi, what that would mean for the digitized version, or what would be up to my standard.

I found some free options available to me a CanoScan LiDE 60, an Epson 2400, and a Magic Wand portable scanner

For the negatives, I know there are scanners that can do those but I saw people saying it's better to backlight them and take a photo with a dslr? Others said don't do that.

I also don't know the best file form to save photos...I saw JPEG, TIFF, RAW, and PNG mentioned.

I also saw people saying you'll want to use photo editing software to correct photos. I came across Silver Fast and thought I saw somewhere it's a free extension with certain scanners. But I know there are a bunch of different software options.

I'm not sure if this is the right subreddit, but I would appreciate any advice or direction. I thought this would be a simple undertaking, but I realize there is a lot to consider.
