Possibly, but Firefox & Chrome based browsers have the same built-in isolation and other security measures as on Windows. Plus you can use Ublock Origins to get rid of malvertisements. If you really wanted, you can also isolate the browser entirely with something like firejail.
Hardend forks like LibreWolf are good too.
Oh, and Wayland also isolates clients from each other too.
I don’t think it’s that big of a threat as long as you keep some level of common sense.
Wayland is a communication protocol that specifies the communication between a display server and its clients, designed to be a replacement for the X11 window system protocol and architecture.
I might be a little nitpicky here, but I feel it’s an important distinction to make as there is no single common Wayland server like Xorg is for X11.
A display server using the Wayland protocol is called a Wayland compositor, as it additionally performs the task of a compositing window manager.
Xorg on the other hand is basically one fat display server designed like a house of cards that everyone uses.
Luckypatchers.com is the real one.
Also you should avoid pureapk, it has malware.
I recommend sticking to apkmirror if the application is available there.
