Religious in my opinion as a concept

Hello, as a preface to my question, I would like to point out that it is clear to me that it can be answered in a dry and shallow manner, but I am specifically addressing you based on my familiarity with your content and lessons in the hope that you can shed some light on the subject from your unique perspective. This subject has been weighing heavily on me lately and connects somewhat with your series on innovation, conservatism, and tradition that I am just finishing and would appreciate a detailed answer and even directions and links for further study. Thanks in advance.
I recently heard from a number of people that I I hold them to be rational and intelligent people who define themselves as semi-religious, “religious in my opinion,” or somewhere on the scale between religious and secular.
I will clarify at the beginning that it is clear to me that no one is perfect and keeps all the commandments, and therefore everyone is not completely religious or is somewhere on the scale (according to a view that would claim that a perfectly religious person is only one who keeps all the commandments).
However, the separation in my opinion is their lack of ambition to be somewhere different.
For example, there are people who are unable to get up for the minyan in the morning but claim that they would like to succeed or strive for it. In the concept I am talking about, there is no such aspiration. For example, it is enough to pray on Shabbat evening and that is it. (I know that this may remind me of classic traditionalists, but it feels like a slightly different and more modern concept to me.)
I will add that personally I have a very hard time with this perception because it would have been much easier for me to be “religious” if I had defined myself as religious who does not observe Shabbat, but I feel that it would be simple to work on myself and it would become that in the end I do what I am comfortable with – if it fits with religion, great, if not then that’s fine too.
On the other hand, I am aware that there are certain commandments that I also don’t really understand and, to be honest, don’t really aspire to keep. In addition, I have difficulty finding a fundamental difference between a person who simply prays in the minyan/does not keep Shabbat because it is not important to him and a person who claims that it is important to him but is unsuccessful (I think it comes down to a matter of priorities and in the end, prayer/keeping Shabbat is not prioritized enough in both cases and there is no fundamental difference between them). Therefore, the difference between the perceptions is a bit unsettling to me, and I would appreciate clarification from you.
In conclusion, of course everyone will do what they feel is right, but I would love to hear your opinion regarding such concepts as “semi-religious,” and especially such concepts that define a new set of rules that both give you comfort (not keeping Shabbat, for example) and also give you a feeling of connection to religion, etc. without telling stories of “I can’t get up to pray,” etc.
