I just soultrapped my first golden saint - which enchantments should I consider taking?

On my way to a quest location I visited a daedric ruin, and on the way out I soultrapped a golden saint, two dremora lords and a flame atronach. This was the first time I was on the road with empty soul gems.

To celebrate this popped cherry, which enchantments should I get?

I play a stealth archer with bound bow (backup: bonemeal) and lean into magic quite a lot. I have about 20 unreasonable fortify intelligence potions remaining from a previous alchemy loop, so I can easily get several thousands of intelligence for the enchant process.

My final weapon is a glass dagger. I have a daedric one in my storage though, which should have higher enchant capacity.

I'm open to constant effects (jewelry is possible) or on use, just any suggestion goes!
