Mi Box S and Google Chromecast 2020 should be fine for 4K 酷喵影视. Google Chromecast 2020 is better as it has faster CPU.
Or you can consider more powerful box with S905X4 CPU, like Mecool KM6 which is running official Google Android TV OS (but not Netflix certified).

Thank you for the recommendations. Yes i have considered both Mi Box S and Google Chromecast 2020, and on top of that also 电视果 by iQiyi.
Chromecast is good for many apps that are outside of china. Eg. Facebook, Netflix, SingTel cast, iQiyi international etc.
As for 电视果, its advantage is to access available iQiyi china content in 4k HDR. And iQiyi china does have several Hollywood shows like Alita, and all the Disney shows that i can think of (Frozen 2, Avengers 4, etc). And it also comes with a free 1 month VIP card. Subsequently i can just get a 1-month VIP card (cheaper than renting a single show on Google Play Video or Amazon Prime) as and when i want to watch any show that is only available in iQiyi and not Youku.
Another advantage of 电视果 is its easy set-up like Mi TV Stick. Just have to attach to the hdmi port and the usb port of the TV and it can work. No need for external power plug. This translates to good portability in the case need to bring it to anywhere outside or even within the house.
One more interesting feature from 电视果 is the 'silent mode'. Allows watching shows on the big screen at night when you do not want to disturb others, but the audio will output from your mobile, and you can listen with earphones.
When it comes to content consumption, i am mainly looking to watch blockbuster movies on the big screen with family members, so i guess Youku subscription + the iQiyi content would suffice. And my smart TV already has built-in Netflix & Youtube, so i guess i can forgo the the chromecast technology.
(If i want to watch anime with awesome sound effects through my home audio system, i can still cast from
some website through dlna. Have tested using my Xiaomi phone's built-in browser and casting to Happycast. I think it will work the same when casting to 电视果. If not, i can always use the 'Web Video Cast' app).
Also, IF one day (probably very far into the future) i were to upgrade my TV, i will most definitely get an Android TV with chromecast built-in. So by then, the 电视果 will still have its advantage.
And finally, just to share that 电视果 will be having a CNY sale when it hits midnight (20 Jan), with 电视果5S priced at just 228Rmb (< S$50).

EDIT (26 Jan)
i realise the 电视果 model in above link is actually not suitable for 酷喵 as it does not have tv box functionality that support apps. Only videos from iQiyi can be casted on TV with <EDIT 31 Jan>
DRM decoding capabilities for high resolutions. Does not apply to any other streaming platforms that restrict
casting of copyrighted videos in high resolution to only their tv apps (Youku, etc).
电视果5S PLUS is the better model that has a number of pre-installed apps, namely the TV ver apps of the popular video streaming platforms. Price-wise around S$6 difference only.
