Baldur's Gate 3

Maybe it would be better not to use combat spells at all? This is a balance of the regular features of a Rogue vs what is actually useful to them. The rogue deals a fair bit of damage in melee combat. No reason to need the shocking grasp cantrip.

Having the dash, disengage, or hide bonus action is great so long as you have for instance a spell that might augment one of those. For instance a spell like Fog Cloud or minor illusion to create an effect that would give you something to hide behind.

You're not high enough level yet to do this with other spells that are higher level on the spell list, but I think this is a matter of thinking about which spells work in conjunction with being a rogue.

Rogues are a bit squishy so using something for extra HP or a spell for protection might be in order (mage armor?). Find familiar might work just to do extra buffs/damage, and give you flanking.

You don't tell us what your race or background is so we can't tell if you have anything extra going for you, but I think you could have fun with this possibly if you change your intent from dealing damage with spells in combat to using spells to augment your class features in combat. Or those of the rest of your party.
