CAD-Software:
Unless something drastically changed - Autodesk Fusion 360 for personal use remains free for as long as you want and as such the only realistic immediate drawback you'll be encountering for keeping it that way will be the 10 Project Limit which depending on how your desired workflow is may not really impact you at all.
Create a Project - Export it ready for Production - Retire it once you've reached the 10 Project Limit - Start new Project - Rinse and Repeat ( untested by me since I'm paying for it 😁 )

IMHO, paying for what one might consider an Industry Standard Software that makes you money shouldn't come with the question if it's worth when it costs like $1⁵⁰ a day ( Probably rich coming from an early adopter locked into paying a paltry $0⁷⁰ and not even making money of his designs but hopefully you still get the point 😏 )

3D Printers:
You'll first want to decide what you'll be using it for... Want to make intricate Scale Parts? SLA or MSLA it will be. Want to make your own large scale Tanks or Fancy Furniture? FDM will be your calling.
If it were like 4-5 years back, I'd have suggested getting a Prusa i3 MK3S I still have lying around collecting dust, but it is now 2023 and quite honestly for the price they're still asking for one ( Kit or Maker forbid Preassembled ) they're what I'd call plain outdated, slow and surprisingly Firmware locked Garbage ( also an atrocity to do maintenance on if something on the Tool Head goes south ).
Personally, I'd suggest getting a like 350% faster than an i3 Voron V2.4 or Trident ( this 200x305x165mm Box was made on a 350 sized V2.4 in 6h38min which would have taken 1d3h on an i3 ) available in various sizes and only using 100% nonproprietary parts, but you'll have to build one yourself and rely on the PIF Program to get a Basic Set of 3D Printed Parts you'll need for the build if you don't already have a 3D Printer to make them yourself.

If building your own 3D Printer isn't to your liking, then my next best guess would be running with the Bambu Lab P1P which arguably comes with the downside of using proprietary consumables ( like the Nozzles ) you can only get from them which is something to think about before putting your trust into them but at least they too will be in the same speed range than the Vorons.

If the prices of both the Voron and Bambu are a no go for you then obviously there'll only be the usual Prusa Clone Suspects out there for like 200.- at comparable speeds of an i3 but at least you'll not be feeling the taste in your mouth of having bought a total rip-off in 2023 ( that being the Prusa i3 ).
Also please don't buy into the E3D Revo System and their also super proprietary Revo design locking you out of the industry ( Uhm... Maker? 🤔 ) standard V6 Nozzle System that allowed for such innovations like the Bondtech CHT Nozzle Design enabling much faster throughput of the Filament and thus faster print times ( if the Machine is capable of supporting that ).
