If you get a MacBook Air it will get quite toasty at throttling limits. After all, it has no fan.
MacBook Pro models and Apple computers in general tend to favor quiet operation over keeping the laptop surface cool.
Many PC gaming laptops go out of their way to keep warm air off the keyboard deck with a high willingness to use fan noise to accomplish that since the assumption is that you’re resting your hands on the computer for an extended period and you have headphones on for your game anyway.
In the specific case of the i7-7700T, the "T" suffix for Intel CPUs usually means you have mainstream desktop silicon with arbitrarily reduced long-term turbo limits, intended to be used in small form factor PCs with limited cooling capacity. Its limitation to 35W sustained and official Tj max of 80°C are artificial and essentially fiction, and the same silicon will readily do 91W sustained with a Tj max of 100°C as seen on the i7-7700K.
Processor temperature under load tells you almost nothing about the power draw or efficiency of the chip, because the temperature can be controlled to almost any value desired through a combination of varying cooling effort and varying clock speeds.
