Meditation Without References

I have previously asked questions on this forum, and now I have gained some familiarity with meditation. I am primarily doing breath meditation. When I practice, my thoughts are barely distractions at all. I can easily stay focused, but I cannot narrow my attention to the sensations at the tip of the nose. What occurs in meditation feels like a clear, yet imprecise awareness. I know from reading on the subject that the sharpness I am looking for comes with gladdening the mind, or applying effort. Yet, neither seem fruitful in my practice. I remain very weakly focused on an imprecise object, more or less the face and nose area. Similarly, it often happens that while meditating my thoughts dissipate completely, or to a near absence. I keep hearing different types of advice, some people experienced in meditation advising me to not use the breath, some people advising sticking to it. Given that I am very avoidant towards experience, I am doubtful towards centring my awareness on a single object. I would like to be more alert and aware, as well as awake, in general. Yet, I cannot visualize anything at all, am mostly emotionally barren, and feel unmotivated in general. I remember applying meditations on emptiness quite intensely in earlier years, and now I feel without much suffering, but also without much enthusiasm. Any thoughts?
