I think most people use "remote work" for the most extreme version where there is no other typical jobsite. The worker works from home, or wherever they choose, and has no regular work-imposed constraints such as onsite meetings with clients. This often applies to worker bee or creative tasks like programming or long-form writing. With teleworking infrastructure, it can also apply to more boiler-room sorts of work which have frequent interaction but no fixed location. People in sales or consulting who nearly always visit other sites used to be called "road warriors" which is definitely not implied by "remote work" in my mind. On the other hand, "work out of a home office" can mean anything. It can be someone with an office who stays home a few days a week or month, or even just works extra hours in early morning or late evening. It can be someone who does visits client sites and has client meetings in public, but keeps their files and records at home because they don't need a storefront. This could include road warriors who lack an assigned space in their nominal place of employment.
