LibreOffice Draw works a treat for some tasks, but it basically converts the file into their format, and the app works like Microsoft Publisher. Then you export back to PDF at the end, if needed.

PDF Arranger is very basic and simple, but it does rotating, cropping, combining etc. And it's open source.

I like Okular but I don't do nearly as much PDF based tasks as some.

I use "PDF Studio" (https://www.qoppa.com/pdfstudio/) and it's great, no problems at all.

Sadly I have to keep one Windows machine with Acrobat installed because the tax authorities here use hideous Cthulhu-like many-tentacled "Dynamic Forms" documents that automatically transform into XML (ugh) and only work in Adobe/Windows. But other than tax returns, I only use PDF Studio.

Been using Sterling PDF for times when I need to edit a PDF https://docs.stirlingpdf.com/Installation/Windows%20Installation

For just viewing or similar edits like rotating I use Okular, it works fine https://okular.kde.org/download/

If you are a LaTeX user, you can actually do this with LaTeX pdfpackages.

I've started using https://bentopdf.com/ seems to have all of those features

You could use ilovepdf ? It's available as a web app for free without an account
