I really like the studies by Bertini and Heller; I find them much more "musical" compared to those of Czerny, Clementi, and Cramer himself. I know that studies are purely pedagogical and sometimes "sonority" can be sacrificed to forge technique, but still...
I would like to listen to something similar to the first two composers, can you recommend or suggest some new listening material?
This type of study goes hand in hand with the progress of technical skills and the development of the student's musical qualities. Recommending "pleasant" studies is not enough; one must see if they are appropriate at that given moment and specifically chosen to bridge certain difficulties to be overcome during the course of study. I don't know what point you are at in your journey, but I would like to emphasize that such compositions, besides being pleasant, have a didactic aspect, and it is important to focus on "how" to approach them rather than just playing them. Therefore, I encourage you to let a Master listen to you in person, as they can suggest something useful. They don't necessarily have to be "studies." Even a Chopin waltz, an easy mazurka, or a fragment of a Mozart sonata teach a lot both musically and technically, but they must be chosen carefully, monitoring "how" they are approached.
Now you will say that you only asked for the names of similar studies and I, as a man of the 1900s and an old-school teacher, have taken it upon myself to convey a broader concept, perhaps not wanted by you. If so, I apologize for being "uncomfortable"... in short... for not minding my own business?... but in my opinion, the one I am illustrating is a good one to follow.

And you are perfectly right; it goes without saying, as you wrote, that I was only looking for new names even just to listen to, combining the useful with the delightful through the discovery of new composers.
Anyway, your words are sacred and thank you very much for sharing
