i use an addon for firefox called Clippings on PC! it lets you right-click and paste stuff you've saved to it in its little config. very handy, i used to use another one for filling forms but it switched to a pay-to-use model which is just kinda bullshit
as for mobile, i use Unexpected Keyboard which now has a clipboard that lets you pin items for later pasting! it's a super cool keyboard outside of that, super configgable but doesn't have any tap sound feedback sadly
