How do I get macOS Sonoma (14.0) to keep the same font size in the finder?

Question

Before MacOS Sonoma, all finder windows showed the same font size

Now, some folders use a much smaller font size

You can even see the font size on the side bar on the left does not match the tiny fon in the list of files and folders on the right.

Note: it's not just folders with files in them that get the small font. Here's a folder with files that's staying with the normal larger bolder font

How do I get Finder to keep the same font everywhere. Ideally the same, larger, bolder font that was used everywhere pre Sonoma?

You might not be able to do this with one single settings change - depending on just how many folders are no longer at defaults.
For comparison, check two or three different folders. the more common setting are most likely to be your usual defaults. It is possible to have different settings remembered for every folder on the Mac, but it's unlikely you've set many differently.
Once you establish your most common, you can then reset your aberrant ones.

Open one or more folders, as you have above.
Hit Cmd ⌘ J or View Menu > Show View Options
You only see one of this window at any time [it's an info sheet known as an Inspector] If you click another folder, the contents change to reflect that window.
In the Inspector window, if you hold Opt ⌥ the 'Use as Defaults' button at the bottom will change to 'Restore to Defaults'.

Default font size is usually 12.
You can, of course, set any values in here to be your new defaults, then save them with 'Use as Defaults'. This affects all windows currently set to default, but not any you have previously customised. This means you can have icon view for apps but list view for documents, etc.

Note: .DS_Store files contain so much more than folder settings & positions. It doesn't really hurt to clear them, but clearing them doesn't always do what you think it will. Resetting individual View options & your Defaults is a much neater solution.
