yeah, SSD will help a lot... it should be a usable system... i had a similar Vaio about 5 years ago, it was nice... my recommendation is to run Cinnamon tho, it's a little heavier than xfce/lxde but it's way prettier, especially with the adapta-gtk-theme installed 

 I’m really a beginner, and the things you’re saying aren’t familiar to me. 🫣
