Looking for Fixed TV Wall Mount for 65"-75" TV + Soundbar

I am looking to wall mount my JVC 65" TV. The TV is getting old and we are expecting to replace it with a new 65"-70" TV within a year.
We wanted to wall mount this TV and ensure the wall mount is compatible with a new standard TV (e.g. a new SONY/HISENSE TV of similar size). We do not need a tilt or swivel, just a static wall mount with our Yamaha YAS-108 mounted below. Bonus points if there is a mount that can also mount the soundbar all in one?

There is a [Kogan Ultra Low Profile Fixed TV Wall Mount for 47" - 90" TVs] (https://www.kogan.com/au/buy/kogan-ultra-low-profile-fixed-w...) for $29.99. Will this do the job? What will a $80 static wall mount do that this cant?

Would [EZYMount VSB-100 Universal Soundbar Bracket] (https://www.jbhifi.com.au/products/ezymount-vsb-100-universa...) $59.95 be useful for mounting the soundbar to the TV without drilling extra holes in the wall?

Thanks for your help!
