I only saw this topic recently. Sorry for replying 2 days after everyone else has left...
------------
I like the pMOS constant-slew rate trick myself.
A number of voltage-regulators have soft-start ramp-up already built in. But if your project doesn't have one, you can build it out of pMOS pretty easily. With just a resistor + capacitor on the pMOS (serving as negative feedback, to slow down the start), you can arbitrarily slow-down inrush current to whatever values you wish.
Constant-slew rate voltage control vs a capacitive load effectively creates current-controlled startup functionality. So its "good enough" for most people's purposes (assuming capacitive loads are what's causing you to be worried).
So its a bit of an A-problem vs B-problem here. I'm giving you a slew-rate controlled soft start circuit when you asked for current control. But... its probably what you want?
> but I'm guessing there must be better integrated solutions (e.g. with temperature protection, etc.)
I believe the "proper" solutions are called a "load switch", of which there are a huge variety of integrated chips and MOSFETs with load-switch (constant slew rate + temperature control) solutions available.
Things get rather complicated as you edge into "proper" solutions. I'm just a hobbyist though, so I don't have much experience with these "proper" designs.
EDIT2: Maybe that NXP Load switch is a bit "too full featured" for most projects. This TI one I found seems to be more mainstream and simple. TPS22950CQDDCRQ1 (https://www.ti.com/product/TPS22950-Q1)
