Here's one more candidate for you that I happened to check out recently:
https://www.pdf24.org/en/.  They have a conversion tool.

They also have both online and offline versions.  While I found it took
some getting used to when it came to the offline interface, it did what I
needed it to do which was to combine PDFs and paginate them.

Btw, it just so happened that I put in a purchase request for a paid
($69.95) alternative to Adobe Acrobat: Master PDF Editor (
https://code-industry.net/masterpdfeditor/).  Adobe has positioned
themselves as a provider that simply no longer offers enough value for me
to put up with all of the things I don't like about them (high price,
subscription-only, background processes you can't get rid of with their
software, etc).
