When you use the Attach Files function, the image is uploaded and placed in your post WHERE THE CURSOR WAS PLACED when you started the upload process.

For example, I have my cursor at the end of this sentence as I click on the Attach Files link below.

 The above photo is from Halloween 1996 when I drove Lurch to work wearing a cow costume. 🤡 I know, utterly ridiculous!

This is a different behavior than the old Attachment Manager, which always placed the image at the bottom of the post.

If you want a pic at the bottom of the post, place the cursor at the bottom when you upload it or them.

I have not seen a way to add a caption to a photo yet. I'll keep looking and keep you posted. (pun intended)
