I really encourage you to use cable glands.
I do and don’t have the slightest problem 🤷 to each their boxes

I feel like cable glands are good at securing wires making clean outlets and preventing larger particle ingress.
Butyl tape is amazing for waterproofing and general liquid ingress.
Seems like the ultimate solution is to use both, and use epoxy for tight spaces where butyl tape is impractical.
The biggest benefit to cable glands IMO is the fact that they’re not permanent. If your motor breaks or something, you can loosen it and pull it out, and tighten it back up when the new motor and wires are in place. Meanwhile trying to pull a cable epoxied to the enclosure is going to be a bad time and most likely a destructive process, making it harder to wire the new one in and keep it watertight.

This, so much this.
Or, you can make it serviceable:

Eh I’ve had connectors ripped out before and you can’t zip tie them together when it goes through an enclosure, glands provide a physical clamp on the cable which helps significantly with stresses. If there’s such things as an affordable waterproof locking connector that can handle the amps while being as low profile as an XT90 I’d use them though.
