On the internet you will find so much that confuses me.
have a budget of 1300 euro
Owned 2 EVLVR 1 TB external hard drives
Need a laptop for cad programs as well as lavish office work screen size 14 inch ideal
and have a sd card slot
mobile stable should have good battery performance and not be overwhelmed when using 2 different applications. Is a pure working laptop
Well, the question is, what kind of screen do you want. Just take the laptop with the best processor your budget gives. Battery capacity is given in watt-hours; you can also compare. RAM at least 8 GB. Had to see if your applications need more. Graphics unit probably does not matter.

The is pretty good for office, only the question arises whether 512 gb memory are sufficient
This is the business version
Way too expensive.
Take a look at the series Travelmate at Acer.
This fits in quite well with your requirements.
