None of that list is specific to Physics. That list isn't even specific to science majors. More broadly, I'm not sure what it means to be an 'expert in Physics'. Physics is too broad for that.
(1) There are different levels of expertise in any field.
(2) The education and training required to reach a specific level of expertise varies with the field (and subfield).
(3) In an earlier post, you stated:

Engineers don't graduate with a generic engineering degree, they obtain degrees in mechanical engineering, electrical engineering, etc. A physics degree is the liberal-arts version of a science degree.

(1) There are schools that offer a "general engineering" major and other broad-based, multi-disciplinary engineering degrees. (2) Physics is not a generic science degree by any means. E.g., you're overlooking at least the major branches of chemistry (and chemical sciences) and biology (and life sciences).

When a Physics major is primarily 'advertised' as "The math and problem-solving skills they pick up are great for the job market. Physics majors teach, work on Wall Street, and serve in the military. They also perform well on the admission tests for law and medical schools." or "One possibly appealing aspect of studying physics is the diversity of physics careers, which are not set in anyone direction. Physics graduates have skills that are in high demand in diverse sectors. These include skills relating to numeracy, problem-solving, data analysis and the communication of complex ideas, as well as a wider understanding of how the world works, on a scientific and human level.", that indicates to me that a Physics major isn't expected to become an expert in anything, but rather a jack-of-all trades.
(4) Let me highlight and expand some key points.
(a) Physics is
not a general science degree. It does
not include, e.g., chemical sciences and life sciences.
(b) There
is a general engineering degree.
(c) At the undergrad (and grad) level, a student typically
does have the option of getting a degree in a specific concentration of engineering (such as EE or ME). But even a major such as EE, e.g., has a broad scope. Typically one does not practice as a general EE: Further expertise in a subfield (such as data networking, semiconductor devices, or power systems) requires additional education (MS or PhD) or training.
(d) At the undergrad (and grad) level, a student typically does
not have the option of getting a degree in a specific concentration of physics (such as solid-state or high-energy) [there are exceptions at some schools]. Typically one does not practice as a general physicist: Further expertise in a subfield requires additional education (typically PhD for physics) or training. Deep expertise is often acquired via the PhD thesis. But the initial required base expertise (broad background) is a major plus.
(e) The situation is similar in other fields, such as law or medicine. One achieves a base level of expertise with a JD or MD. Typically one does not practice as a general JD or MD: Further expertise in a subfield (such as patent law for a JD or neurosurgery for a MD) requires additional education or training.
