In a similar dilemma, but nothing critical and not that worried.
I'm not that convinced disk is that future proof. There's a tendency to mess about with everything today, one minute frame fittings work with available parts, next minute either the parts cease to be made or the frame fittings change again.
At least with rim brakes you know where you stand, parts will be available for time to come, and there are bargains to be had as fashion moves on.
I'd say the brifter is the most critical part to stock up on regardless. For me it feels you get caught out by either the brake technology or the incessant "adding one extra sprocket". There are also ceramic rims of course which last a long time.
