full UI/UX behaviour that behaves almost identical to Windows/Mac

You want Windows or Mac.

If you want a computer that you can do stuff like web-browsing, document/spreadsheet/pdf/slideshow editing/creation, gaming, or multimedia processing on, there are distros and utilities on Linux that make those more-or-less easy and beginner-friendly,

BUT it requires divesting oneself of the habits, behaviors, and paradigms of other operating systems and being willing to learn anew. Community-based Libre software is developed in an entirely different way for an entirely different purpose; because of that, it is nearly impossible to recreate the same software as for-profit proprietary software. One is made by a community hacking together a functional system that suits their needs, the other is made to generate revenue, and thus has to keep users dependent on it by trapping them in dark patterns and igorance of its workings.

If you just want “Mac or Windows, but free as in beer,” suck it up, pay the devil his due, and buy one of those OSes. Libre Software is an entirely different paradigm, and thus requires a whole paradigm shift before anyone will be happy with it; on-boarding people who aren’t ready to divest themselves of the old paradigm just leads to disgruntled users who blame you for anything wrong with their PC, and creates a market void in the FOSS community ready to be filled by corpo proprietary slopware.
