Notebook for music, office automation and light gaming ~ 800 euros

I plan to buy a laptop for the next month, as I will probably be traveling more in the coming months and years than before. Here the focus is on music production, office and light gaming.

1. What do you want to use your laptop for? Commercial or private use?
Use it on the go because I have a gaming PC at home.

1.1. Do you want to use the laptop primarily mobile or stationary? How mobile should the laptop be? Should it be a 2-in-1 notebook/convertible?
Mobile, normal laptop is enough.

1.2. If you want to play games: what games? What level of detail?
Easy games: WoW, Genshin Impact, Valorant, Crusader Kings 3 and company. I’m also happy to compromise on the quality of the graphics here.

1.3. Music/image/video editing or CAD: which software? Professional or hobbyist?
Music production with FL-Studio, if necessary light image editing.

2. How big should the screen be? Do you want a touch screen or a particularly high display quality?
min 14 inches would be great. But don’t limit me here.

3. How long should the battery last?
Don’t commit me here, 6 to 8 hours would be desirable.

4. What operating system do you want to use? Is there a license? Does the laptop already have an operating system pre-installed? Do you get Windows through college?
Uni license for Windows is available.

5. Do you have any wishes regarding design, processing quality, material or colour?
Preferably not too heavy/squat

6. Are there any other special requirements that were not asked about? Big hard drive? numeric keyboard? keyboard backlight? pen holder? Docking via USB-C/Thunderbolt 3? CD/DVD drive? Discounts (educational)? Service and warranty? maintenance options? SD card reader?
get student discount.

7. How much money are you willing to spend? Is buying used an option?
Below 1000 euros, optimally in the range of 700 to 800 euros.

Thanks in advance for your ideas!
