Probability of actually realizing significantly outsized-carry on a 30-year career trajectory (converted to real-cash) across different grades of London/German/Swiss/French PE firms

This is inspired by a similar trending thread with regards to American PE. First, what category of PE firms in London/Europe have the best upward mobility chances (towards partner perhaps); is it MFPE or LMM or below? Second, what category of London/Europe PE firms tend to give one the best or relatively higher chance of outsized long term comp (including carry) on a multi-decade (35-year) career trajectory starting out as a post-IB associate? Third, but related to the former question, what is the long term job security like for London/Europe LMM PE in comparison to London MFPE? Fourth, is it true that MFPE is the only category in London/Europe that allows you significantly higher carry percentage at the senior level (than MM)—due to deal size? Fifth, is it true that there is far less turnover near the peak of the PE career in London in recent decades—as compared to earlier (pioneering?) times? Sixth, what controllable factors can a junior professional work on to maximize chances of upward mobility – as opposed to getting fired down the line? Seventh, given the current PE market trends, what kinds of PE firms (MF vs MM) are likely to perform better than others, and/or what sectors are more likely to outperform in PE in the mid–long term in Europe? I recognize most questions would be naive, and that there is more likely to be heterogeneity across different regions of Europe in regard to these questions—therefore—all takes from different nationals are welcome.
