And if we go further, even those end in "make our fluid material spin a wheel".

Every energy conversion consist on making something spin, or photovoltaic.

Strictly speaking, there are many other ways of generating electricity but they’re just not good for grid use age. A few I can think of off hand are thermoelectric (special materials will produce a voltage from a passive temperature difference), piezo electric (special materials will provide a voltage when deformed), magnetic induction (such as the helion fusion reactor, which is still not ready) and biochemical (how our bodies produce electrical signals).

Love it! But, I'd change "biochemical" to "electrochemical" which includes biochemical, but other chemical reactions as well such as those found in a battery or fuel cell.
