Yes puthujjanas claim that good mediation means not clinging to thoughts and lack of ''doer'', of ''agency'', of ''knower'' especially the intellectual puthujjanas who invented the dry insights. That's cute but it is not the discriminant between good and bad meditation.
As usual the discriminant between a successful ''meditation'' and a failure is about kama, sensuality, but philosophers always try to switch the topic towards thoughts and mental masturbation, and they never judge through kama and lack of kama, through Virāgā, and even less through knowing the conditions of what is conditioned.
SO at the very best your are like this bikkhu
"Having abandoned sensual desire for past sensual pleasures, lord,
having done away with sensual desire for future sensual pleasures, and
having thoroughly subdued perceptions of irritation with regard to
internal & external events, I breathe in mindfully and breathe out
mindfully."[1]
which is better than being a mindless, lustful puthujjana, but the vipassana are the next steps, which is as usual knowing the origin of whatever is conditioned, knowing what is conditioned and knowing the cessation of what is conditioned, typically the origin of lust, raga, the cessation of lust, Virāgā, relinquishment and so on.

so once you want the vipassanas, you first superficially calm the body, the citta and the mano, which just mean casually being relaxed, then you need as usual the joy to deeply calm whatever is still agitated, to switch between rupa and citta. Once the focus is on the citta, you can become sensitive to any sankhara left and as usual, the goal is to calm these sankharas (with sati and wisdom of course) because sankharas are always bad, then as always joy, pleasure remain and right samadhi is established, and then to see how those sankaharas and 5 aggregates and dukkha arise and under what condition they are destroyed, to focus on dispassion, on fading away, on relinquishment, on cessation, on rejection.
Trying to get the vipassanas without right samadhi is too difficult for most puthujjanas, since most puthujjanas are just too lustful, too mindless.
