Wiska are an excellent choice
Wiska offer the best for IP protection and functionality with multiple entry points. As a time served electrician, these are my go to brand for external cable enclosures.

Wiska boxes are the best
These weatherproof electrical junction boxes are excellent quality and so easy to use. The fact that you can just screw in the glands makes their use and assembly so simple and easy. I highly recommend these and don't forget to use Wago connectors too - they take the effort of joining cables.

A bit tight for space inside
I'm a keen DIY-er so managed to use this, although in hindsight, I'd have gone for a box that is slightly larger inside. Pros: 1. Strong plastic construction that I don't think will crack. 2. Front 4 screws seal the front of the unit nicely. 3. Comes with a connector block inside. Cons: 1. There was only just enough space inside the connector box to connect my 6mm SWA cable to the cable going through my wall. In making the connections, I could not seat the connector block onto the slots where it should really go within the unit, but I could have it "loose" inside and seal the front of the unit properly. 2. I'm not confident about the waterproofness of the rear of the unit, even with a suitable grommet, hence the black sealant in the photo (which I wish I hadn't done because it's a bit untidy).
