For fast prototyping I’ve started using jlpcb.com and even moved from Eagle to their easyeda designer - having a library of components that are in stock, without having to find and verify the footprint makes it a thousand times easier, even if the design software is pretty basic.
Save the BoM and P&P files and then convert them using the above as a filter, save the stdout into new files and upload them at a step where it asks you for these two files. This makes the process from design to order quite seamless for me.
I also use this to fix some of the orientations that are apparently incorrect in their database.

[ 3.2 ms ] story [ 22.6 ms ] thread- Calculate your trace widths (based on heat/current requirements and copper weight - there are online calculators that do fine).
- USB data lines require controlled impedances, check your fab for a trace width calculator.
- Don't forget via sizes, the default in your CAD tool is probably too small
- Check your fab for their design rules instead of using rules of thumb
- 4 layer boards are cheap enough for hobbyists today, don't be afraid of them
