Yeah, I've got them for the past couple of years as the PC version has gotten to the point of being considerably too much now (as you said) and my Macbook being old (10 years), so would struggle to get far on it.
It's very stripped back. There's none of the media malarky, your staff are literally bronze, silver or gold with aptitude levels of poor, normal or natural and the tactical side is stripped back as well (no dynamics either). The transfer system is stripped back though you do have negotiations and can have player exchanges, sell on clauses etc.
Overall, it is considerably stripped back and there are only 30 seasons tops, though you do have challenges and you can go through a season quickly as well. I'd check on YouTube just to see if you think you'd like it but I've been happy with it.
Alternatively, @The Palace Fan has had high praise for the Touch version, which is like a half way point between the mobile and PC versions (it has been stripped back a bit but looks and plays more like the PC version than mobile).
Not sure if you have a Switch but the Touch version is available for that.
It's not terrible but it's lacking if you want the main experience as you mentioned below.
