I'm about to build a PC for work. What accessories to buy?

Question

Computers

In general, I'm going to build myself a desktop PC to work with VERY large music projects and not very large video editing. Sometimes even play with toys. Well, that's not necessary. The graphics card is the last thing that worries me, but I would like to choose a motherboard so that I can upgrade to the GPU later. I want to collect for a fairly long future (5-7 years). After a short search, I decided to stop at the following components:
- Motherboard Gigabyte Z370P D3 (s1151, Intel Z370, PCI-Ex16)
- Processor Intel Core i7-8700 3.2GHz/8GT/s/12MB
- RAM HyperX DDR4-2666 32768MB PC4-21300
These are the components that concern me the most and I would like to know if I chose them correctly in terms of compatibility? Then I ask for help with choosing a video card and with a power supply unit. Regarding the second - I think you need at least 700 watts. In principle, on the components, I think I can handle it myself ...
