Consider this model if you want light but not too much:

But beleive me, when you put light in your computer, you will want more.
As far as I can see, Z390E has:
- CPU_FAN
- CPU_OPT
- CHA_FAN1
- CHA_FAN2
- M2_FAN
These are fan headers for internal fans. No more headers. In Asus software you can choose what fan header is connected to what position. So, you can program them separately.
By the way, I have 6 fans and all are connected to one header through hub. No need to use more headers.
But you can connect with splitter few fans on one header and few fans on other header and then apply them to position on software and program RPM for certain position. Check this link:

For myself I bought cooler master fans. They have their own programmable controller, but they use standard PWM header for power and standard ARGB header (or RGB if fan is RGB) for color. So, they are easy to use. Ofcourse, that is my choise, I wanted my mobo to control them all.
For example to make you clear, you can connect bottom fan on CHA_FAN1, front fans on CHA_FAN2. Then you can add them in AI SUITE to that position you placed them. Than you can program them. For exeample, if temperature of CPU is higher than 50C, front fans start to blows more. Then you can program other header if mobo temperature reaches 40C, then other header blows connected fans to 80% for example. That is why you have so many headers.
The best solution is always the simplest one. Dont go with different technologies on FANS and RGB (or ARGB). Chose only one. If you have mobo which support ARGB and RGB, why not use its headers?
If you buy splitter for fans, you can connect them easily. Also you can use splitter cable. All fans are same, one cable for power, one for rgb. If Corsair are easy to connect, the others are east to connect as well. That is my opinion.
So, first chose you fan technology: RGB or ARGB
Then, chose if you fans would run always on constant speed (3 PIN fans) or you want to control them (4 PIN PWM fans)
Check your case manual and see how many position have for installing fans and what size of fan is available for that position and then go to shopping.
Put everything on paper and don't hurry.
It is your hobby after all? You have to enjoy it.
