Best broker(s) in Belgium for a student? (Degiro, Saxo, MeDirect or something else?)

Hey everyone,
I'm a student living on my own, so I've got enough free time to handle things like executing trades or dealing with tax paperwork if needed. I’ve been investing a bit via my traditional bank for the past few months, but the fees are way too high and eating into my returns. So I feel like it’s time to do go trough a broker so I make more money and can buy and sell when I want.

My plan is to buy ETFs regularly and also trade some individual stocks on the side.

I have a few questions and am open to other broker recommendations too:
-Degiro vs. Saxo: People recommend Degiro because of the low fees, but I'm doubting if it's worth the hassle compared to Belgian brokers. Saxo handles taxes (like the stock exchange tax) automatically, whereas with foreign brokers like Degiro you sometimes have to figure that out yourself. Is the savings on Degiro worth the extra administrative work? I don’t necessarily mind if the paperwork takes some time, I’m more focus on how difficult it is, I don’t want to forget one small thing and get a huge fine.

-Splitting across two brokers: Does it make sense to use two? For example, using MeDirect for free ETFs and another broker for individual stocks? Or is that just overcomplicating things with multiple accounts and taxes?

Any other recommendations? Are there better alternatives for someone in Belgium starting out with a student like budget? The last 2-3 years I’ve done 150/ month and than a one time individual stock.

Also, for the individual stocks I suppose it would be nice to know if I can buy partial stocks. But ofcourse it depends on the situation.

Keep in mind I’m no expert so if possible don’t use all the difficult terms at once😅
All help/info is greatly appreciated.
