Medical device engineer here (mechanical engineering). I host jellyfin, game servers (Minecraft, factorio, valheim, etc), my website, and a bunch of other minor services I find useful.
I got into it originally through a combination of poor internet, and being fed up with Google and others discontinuing products/features. The internet problem is solved now, so my only goal is not being reliant on someone else’s cloud.
I’m a Creo Parametric man myself. Used it for many years at a previous employee and loved it. Bit of a learning curve, but you can do just about anything with it. Very powerful.
Currently stuck with solidworks at my current job. Not a huge fan, both stability and tool options are lower, but it works.
Of course neither of these options are reasonable for personal use due to pricing being too high for most people. If you are an active student, you can get free Creo!
'51 truck and '63 tractor here - you’d be surprised! For the majority of standardized things (seals, bolts, bulbs, etc) it’s easy enough to find a cross reference table, and just order the part from napa or Grainger.
For more specialized things (like if you break an input shaft), eBay or any number if specialized stores online will have original parts that have just been sitting in a warehouse for the past 70 years. Here’s one of my main sources for the truck: https://shop.midwestmilitary.com/product-category/m37/
Occasionally I do have to fabricate a replacement.
Actual budget does do that! You can tie it to automatically import transactions via SimpleFIN.

Some things you’ll need to manually do, like real estate valuations.
