Atlas IS the correct way - it's not a workaround ;). However, if
you're after an expression, then use a combination of getFeature and
attribute. This is how it works:

First, use getFeature to find a matching feature from a layer:
getFeature( 'my_layer', 'id_field', 5)
This will return the feature from "my_layer" with the attribute
"id_field" equal to 5.

Next, chain this into attribute:
attribute( getFeature( 'my_layer', 'id_field', 5) , 'feature_name')

This will return the value stored in the attribute "feature_name" from
the matching feature from "my_layer".

Hope that helps!
