Is it because what we’re saying is: it is days like this one, and all others like it, that collectively (followed by 3rd person plural verb form)?

It's is a dummy pronoun contracted with the verb is. In situations where English syntax demands a subject but there aren't better options for a subject, it can act non-referentially to jump-start the sentence. For instance, in

It is raining

nothing specific is being referred to as raining. That is just how we express a state of weather: it's idiomatic.

The dummy pronoun is used with several kinds of statements, including those referring to time ("Dummy Pronouns," Lund University). It's can be followed by a singular or plural verb, e.g.,

It's a year I'll never forget.

It's 5 minutes I'll never get back.

As for days like this [day] versus days like these [days], the choice depends on whether you are thinking of one specific day or an indeterminate series of days. You could use either, as Ngram results illustrate:

It's days like this ...

It's days like these ...

Consider a sentence like this one:

It is days like these that always prove most difficult.

In this sentence, the word it isn't acting as an ordinary referential pronoun; it doesn't refer to the "days" or to anything else. Instead, it's part of a construction known as an it-cleft. In this construction, the singular pronoun it is used as the subject of to be, so to be has to be singular in form. But this pronoun is just a placeholder; it stands in for something defined by the relative clause at the end of the sentence, which is equivalent in meaning to "The x such that x always prove most difficult = these days."

(My source for the above is Huddleston & Pullum (2002), pp. 1414-1420.)
