Seconded on Sofle, though Moonlander would be a good choice too. Having the numrow helps ease the transition and reduces the chances that you give up on ergo splits. If you buy a 50+ split and later get the minimalist bug, you can change your keymap to test drive a numrowless layout.
I use Sofle V2 for WFH. I started with a Lily58 at the beginning of the pandemic because I was getting shoulder and wrist pain from using a TKL all day. I liked the Lily58, but I also have big hands and found the thumb cluster cramped and the stagger too shallow. The Sofle V2 is nearly the same layout except the thumb row is moved out by a column for more natural thumb placement. I’ve been using the Sofle for a little over a year now and am planning to build another for the 1 day a week I need to drive into work to hotdesk.
QMK is great, but I switched to VIAL, which is a fork of QMK that allows for on-the-fly keymap changes from an app without having to recompile.
OP, DM me at al177 on Discord if you’re in the US and decide to DIY a Sofle. I have extra unpopulated V2 main PCBs (not top or bottom tho) and would be glad to send you a pair to get you started. I also have a Lily58 I would part with for cheap.
