Catalina can only run 64-bit executable code, and won't run older 32-bit code. If you have any software that runs as 32-bit binaries, with no updates available to 64-bit versions, then you may prefer to run Mojave (10.14) instead of Catalina.

You should always download from Apple and nowhere else. But now is a good time in the 'annual cycle' to update, as Catalina is on its sixth and final release, so it's as good as it's going to get. There will always be unresolved bugs in any OS. The bad news is that some companies may require payment for newer versions. Dropbox and other cloud services all have current versions. Apple, as you would expect, has current versions of KeyNote, Pages and Numbers. The good news is that any company still in business is likely to have current versions. You will almost certainly have to update all your apps to match the OS, so you should check that there is a version compatible with the latest macOS (Catalina) for each one. Upgrading 'one big jump' from very old software is more difficult than just 'the next version', because the change is so much larger.

I am not sure the cloud services I am using, like Dropbox, will not work after the update. Or non-Apple programs, like Mathematica 9, or MikTex. I am afraid that after upgrade some apps won't work or will be missing. I heard it is not a good idea to upgrade to the last OS (possible unresolved bugs, incompatible with some of my older programs). Here are some comments revealing my ignorance, to help you Mac experts guide me: Question: Can you give some advice/tips how to best perform this task? This is the 1st time I am doing this since I acquired this laptop and would like to do it myself (we don't have good Apple support here).
