Video is good but... The image quality part is kind of meh. And the price part too. 90 to 95% of cameras with micro 4/3 sensor or more are going to have really good to great IQ (even some 1 inch sensors are great). With a sensor starting at 16mpx (even 12) it will be enough for most applications (even professional ones and printing) so it would be okay for family pics. Witch means most cameras from the last 10 years could do the job, in term of IQ. The smaller the sensor, the worst low light performance you gonna get but again it can be okay starting in the micro 4/3 range. I shoot a lot in low light professionally on APSC (a lot of plays and some concerts in very dark environments) with my X-T4 and X-S10. They’re both more than ok for my job. I also shoot my family a lot (they say too much) with this gear, mostly with the lighter X-S10. I got splendid results! The bigger difference would be in the lenses, having good glass will get your results from good to great and you can compensate the low light problems with fast glass (f1.4 to f2 prime lenses). What would make the difference would be the autofocus, you should get a good one for family photos, but you don’t need the best one absolutely. Especially if you don’t do a lot of video (most older cameras have good photo AF but bad video AF, especially Fuji and some micro 4/3). All of this to say, to look at the used market first. You don’t need to break the bank to get a stunning camera and lens(es) if you go on the used market instead of buying brand new. Plus you can get high end cameras, with lots of options. For example, as a fuji user, I know that an X-T3 or 4 (used) will cost you a lot less than the latest release, an X-T50, but you would have WR, a much better battery (for the X-T4), a better built body (with children it can be very important), a lot better viewfinder, etc. The X-T50 would only give you a lot more mega pixels (that you don’t need) and better AF. And if you don’t need the high end specs, an X-T30 cost even less than an X-T3. If you want to spend money, fine, but in my photography it has never helped me to shoot more. In fact, with my family, it may be less, cuz I don’t want expensive gear near my very carefree children. That’s why I am gonna "upgrade" to an even older, cheaper camera than my X-S10 (witch I already bought used).
