Happy to help! For the G502 upgrade, I personally love the G502 X PLUS, but if you want wired specifically or just a more budget friendly option the G502 X will serve you well!
Given the G613 is a full sized keyboard(and for editing/programming) I'd recommend the G915 X if you are willing to give low profile a chance. You can choose between tactile, linear, and clicky, and you can use Keycontrol to set up macros/bindings/whatever you want for ease of use too.
