Understanding Rūparāgo and Arūparāgo

In the Theravada tradition, the fetters model makes reference to rūparāgo and arūparāgo found in the higher fetters. I've never been a jhana follower, but I can clearly recognise that the rupa jhanas and the arupa ayatanas move into me from time to time and sometimes in sequence, one after the other. From early in my practice I noticed they had there own type of sensual craving not particularly connected with dense forms. I found this to be a suitable motivational incentive to move away from desire for worldly form but soon saw the drawbacks of having too much emphasis on rupa jhanas and rupa ayatanas. As such, I developed an indifference about their perceived feeling-tones, but I was still able to utilize the benefits they bring concerning insight and wisdom. My main practice is satipattana. There is an interpretation I came to naturally understand using the aggregates model alongside my here-and-now experience, that one craves either the perception of form or the perception formless both through objectification of mental ideas born from the study of dhamma and the motion of practice. One could use the term *spiritual materialism* as an umbrella term. I find this practice helpful but too tricky to compile into words. To summarise, it's just a granular way of watching the rise and fall of the aggregates. My question is, what other interpretations can be given to rūparāgo and arūparāgo from within Theravada traditions and also other Buddhist traditions?
