1) for a longer time, InDesign is slow (terrible) with opening 2 brochures together (60 pages each) on Windows 10 (Dell/i5/8G laptop or Lenovo i7, 16 GB, both SSD). In the past (CS6) was performance incredibly better... I was forced to change to MacBook (m1) now (because of slow performance) and there is everything OK. You should (maybe) change recommendations on PC.
2) Text to curve causes duplicating object (so it is unusable).
I admire your innovative way with CreativeCloud but don't forget that we have to use it every day - and it is sometimes quite impossible.
That said, while I think your Dell is underpowered for running Adobe apps, the Lenovo is not, and I would not expect serious performance issues with either unless there is some other underlying configuaration issue, perhaps insufficient open drive space for Windows swap files and other temporary files.
