For font size, you can use FONT_RAMP. It's global, meaning all books on the device (which must be in the azw3 format, as FONT_RAMP doesn't work with KFX).

Conversion options are trickier, because the individual css of books can be pretty different. You can set your preferences in Preferences -> Common Options -> Look & Feel -> Styling -> Extra CSS (for example, body {line-height: 2em}, but the book css may override this on the paragraph level. So you should first remove all the css styles you want to override (put line-height in the box Select what style information you want completely removed -> Other CSS Properties and convert epub to epub. Then convert the resulting epub to azw3 and now delete line-height from the box you put it in while doing the first conversion, so that the extra css you specified in the common options can do its thing.

All this can be done in bulk, no need to do it one by one.
