Your points reinforce and complement mine.
If the Navy gets down-sized or repurposed a lot of the personnel would end up in the Space Force *alongside* the repurposed USAF personnel. They would be the ones with both military training and the necessary management skills. Technical skills can be taught quickly but people skills require experience.
(Or national equivalents if the story involves a different nation-state. Of course, that would require the country to have a Navy, which might be an itsy-bitsy problem for Switzerland.
One TV SF series that took a good crack at this question was the late and very lamented SPACE: ABOVE AND BEYOND. They had a blend of personnel and cultures for their mid-term Space Navy.
