I think the clever people he has gathered up will do the heavy lifting and he will adopt a ................. oooh, can't think of the word...........a bit less hands on, only being wheeled out once the "I's" are dotted, and the "T's" are crossed.
He has gathered a well experienced, and qualified team around him. They mostly all have previous DC experience so they will already know the players, and have names, and numbers in their filofaxes. The Orange Don could not fill a lot of the posts in Govt. because people knew that they would have the stigma of working for him following them around for the rest of their careers. I don't think Biden will have any problems getting people to jump into posts, whilst there is a big mess to clean up I think they will give it their all.
You raise an interesting point, the president of the US is like the CEO of a huge multinational corporation, he has hundreds, thousands of very well-experienced people at senior and middle management level to do most of the work, and given fairly broad instructions can for the most part be safely left to get on with it.
The president in the US has little role in the internal affairs of states and cities. Unless there is some extremely urgent business, in the shape of a Russian cruise missile appearing on the horizon, there is actually very little of huge importance that he needs to do all day. He has his briefing with his chief of staff, makes a few decisions on the important issues of the day. If he hasn't a clue what to do (and let's face it politicians are no more likely to be clued in on every single aspect of international and national affairs than anyone else is) he can call on any of the greatest experts on the issue within minutes and get some pretty good advice from them, make a decision and tell his people to crack on with it.
Trump was in many ways a micro-manager, sticking his nose into things that were often below his level and which he should have either left his man on the spot to get on with or replace him and tell the new guy to get on with. That is why Trump was so often criticised for things that really weren't his fault, if he'd just shut up he'd have deflected so much of the fall out.
Like a CEO the president is for the most part the ornamental aspect of the government, the guy that shows up for summits when 95% of the work has been done, hammers out the last remaining points with his counterparts and then stands for the set piece photos. That aspect of the job Biden will handle well enough, that and appointing the right people, which again will be pretty much handled by his subordinates.
And you know, well enough is pretty much all you need from a president or CEO.
