Tyres for hardtail

Hi there

Total novice wanting a bit of advice.

I have a hardtail Haibike freed 7.10 with Maxxis Shortys - 27.5 x 2.3. It’s a carbon bike so quite light but I t’s been sat around for a while and the tyres have had it, cracks on the walls etc.

I’m looking to replace but I’m so confused! I ride mostly dry trails and the occasional bit of mud.

What are the best all round tyres you suggest?

Also would 27.5 x 2.4 fit? Or do I need to stick with 2.3? Also I want to stay tubeless.

Many thanks 🙏
