I dont like straight espresso either and am usually a cap drinker, mainly cause I like the challenge of getting good microfoam. However I have found that I quite like a Macchiato which is an espresso with a touch of milk. I find the milk takes the edge of the espresso but I also get a better indication of true bean quality than the milkier cap. As the only coffee drinker in the house I am always making double caps for myself due to the use of a double filter. This has over time increased my tolerance to stronger coffee and led to the Macchiato as a good alternative. You might find the Macchiato as a good starter.
