Is my PI reducing my chances to pursue an academic career?

I am a PhD student in Bioinformatics and I am approaching my 4th and last year of my PhD. For context, I am from EU country X doing a PhD in EU country Y. I really love doing research and my plan is to pursue an academic career. However, I am really scared that what I have (not) achieved so far will leave a mark for the rest of my career. What I mean by that is that I haven't yet published a single first author paper, even though I am working on the same thing since the beginning. My current project was supposed to be a shared first authorship with a colleague from another research group, but due to internal problems he ended up publishing separately (with me as second author). This type of data is very hard to work with, and for a year now I have been told that "we need to dig into the data", "we need to make it more translational", "what if you did like this or that?" and so on. This way the timeline for publishing gets more and more diluted and I can't meet the deadlines because I have to repeat stuff or add something new. To wrap it up, this is making me "waste" time that I could have used on something else, maybe ending up in a paper. In parallel, I have worked with a colleague on a small method that addresses a bias of comparable tools. It's a very nice story: from finding the problem in the data and to showing ways to correct for it. We both agreed that this deserves a paper. It doesn't need to be grand, but it's for sure interesting and relevant. However, we had several meetings with our PI to convince them of this, with them pushing against because "it's maybe not that important", we "don't have time for this". They basically want to attach it to another paper, resulting in one paper less for the lab and for me and my colleague. And this dynamic of never putting a full stop to something really affects all of our projects in the lab. And because I need articles to pursue a career in university, I am super worried that in this way I will never be able to make it. And what is also bad is that our PI doesn't realize apparently, and even if I told them my concerns in terms of personal development, they reduce the problem to "papers are not everything". Reality is they are, especially when you graduate from a lab that does not have recognition. What do you suggest to try and have some more chances after the PhD?
