Should I bother getting a switch lite in 2024?

Hello all! I am considering buying a switch lite to mod specifically to play Pokemon games because I just ran through all possible games I could on my 3ds XL. I currently have an unmodded switch that I am using for nintendo switch online and was wondering if Pokemon trading would work at all between the two consoles.

Another concern I have about modding a switch is where I should take it to get it done. Modding a switch seems much more complicated than the relatively easy step-by-step process the 3ds had and I really don’t trust myself doing it on my own. So is there any website/person I should reach out to to get it done?

Finally, I was debating on whether or not I should even bother spending money on a current-gen switch at all, considering the fact that the next-gen model will be coming out by the end of March.

Thank you everyone for all your help. Sorry for all the questions as these have probably been answered many times in the past
