I'm considering buying a MacBook to use away from home because my iPad cannot handle some tasks I need to finish. I would probably connect the MacBook to my phone's personal hotspot for around four hours at a time. How much mobile data should I expect it to use, and would I need a large or high-speed data plan? I've seen claims that a laptop can consume about 4 GB per hour, but I'm not sure whether that applies to normal web browsing or to more demanding activities. My intended use would mainly be browsing and general work, not 4K video streaming. Would the usage be significantly different from using an iPad?

There isn’t a fixed amount of data that a MacBook uses per hour. It depends almost entirely on what you’re doing. Basic browsing and office work may use relatively little, while video streaming, cloud backups, large downloads, software updates, and apps running in the background can use a lot. A MacBook may consume more than an iPad if you multitask or run heavier applications, but it won’t automatically use 4 GB per hour.
The best estimate is to test it on your home Wi-Fi first. Use the MacBook for a typical four-hour session, then check the router’s data-usage statistics or the MacBook’s network-usage information. That will give you a much more useful estimate than a generic number, because your actual browsing habits and background applications determine the result.
The 4 GB-per-hour figure is only realistic for certain data-heavy activities, such as high-resolution video streaming or large downloads. Ordinary web browsing is usually far below that, although image-heavy sites and web applications can still add up over several hours. Turn off automatic updates and cloud synchronization while using the hotspot, and set the connection as metered if the operating system or app supports that.
If you need several hours of connectivity regularly and your phone plan has a limited data allowance, a dedicated 5G home-internet box could be worth comparing. Some plans offer unlimited data for a monthly fee, but for occasional browsing, a normal hotspot plan may be sufficient. The important distinction is data allowance, not simply connection speed.

That makes sense. My usage would mainly be browsing and regular work, so I’ll try to measure it rather than assume a fixed hourly amount.
