Perhaps I'm confused or missing something, but given the OP's bio, I didn't take it that they were asking for advice, but rather, just asking about experiences from those who walked last year; perhaps because of the Covid restrictions?
I walked the
Camino Frances (2nd time) from Sept 9th to October 21st, last year. I started in Roncesvalles, walked to Santiago, and then after a couple of days rest, on to Muxia and Finisterre. My personal experience was that of 33 nights spent in albergues, 18 of them
did provide an option to buy and eat dinner on premises, and 10 of the 18 were
not open to the general public and were communal dinners at a set time. None of the 33 allowed use of the kitchen to prepare your own meal, but a few did allow you to bring a meal (like a bocadillo or similar) into the common area to eat it. Standout meals for me were the communal meals at Cautro Cantones in Belorado, Molino Galochas in Villavente, and the completely vegetarian dinner at Ecologio El Beso, in A Balsa (just outside Triacastela). There were 3 albergues where the food itself was just not very good.
In terms of breakfast, about a third of the albergues provided a 'breakfast' to purchase of toast and coffee, maybe a packaged pastry. The vast majority of the time I elected to walk first and but 'breakfast' at the first bar/town we came to.
Sidenote: Though beds were limited to 50% capacity because of Covid regulations, communal meals were spent mostly sitting together, side by side.
