What do you think about leaving out the section #iris-norm? Would conforming to 3987's sections 3.1-3.2 (#server-iris-to-http, #server-iris-from-http ) suffice?

Not a good idea. I specifically wrote this out explicitly because [A] the conversion in RFC3987 is not deterministic (it leaves certain choices, which is a one of the big issues opposers like WHATWG have with it), and [B] these steps should be compatible with both RFC3987 and WHATWG URL. Of course, in practices, a single deterministic URI/IRI spec would exists to which we can simply refer, but it doesn't.

When a server conforms to 3987's sections 3.1-3.2 (#server-iris-to-http , #server-iris-from-http), does it satisfy the #server-iris-norm requirement? If so, can #server-iris-norm be removed?

As clarified in reply to your other comment, it does not in all cases.

What do you think about reusing the language from 3987 (section 3.2's "Converting"):

Suggested change
<p><span about="" id="server-iris-from-http" rel="spec:requirement" resource="#server-iris-from-http"><span property="spec:statement">When interpreting a URI in an <a href=#http>HTTP</a> message, except in the content, as a resource identifier, a Solid <span rel="spec:requirementSubject" resource="#Server">server</span> <span rel="spec:requirementLevel" resource="spec:MUST">MUST</span> map the URI to an IRI according to the algorithm provided by [<cite><a class="bibref" href="#bib-rfc3987">RFC3987</a></cite>] (<a href="https://datatracker.ietf.org/doc/html/rfc3987#section-3.2">section 3.2</a>), and normalize the resulting IRI to the <a href="#iris-norm">normal form</a> provided in this section.</span></span></p>
<p><span about="" id="server-iris-from-http" rel="spec:requirement" resource="#server-iris-from-http"><span property="spec:statement">When interpreting a URI in an <a href=#http>HTTP</a> message, except in the content, as a resource identifier, a Solid <span rel="spec:requirementSubject" resource="#Server">server</span> <span rel="spec:requirementLevel" resource="spec:MUST">MUST</span> convert the URI to an IRI according to the algorithm provided by [<cite><a class="bibref" href="#bib-rfc3987">RFC3987</a></cite>] (<a href="https://datatracker.ietf.org/doc/html/rfc3987#section-3.2">section 3.2</a>), and normalize the resulting IRI to the <a href="#iris-norm">normal form</a> provided in this section.</span></span></p>

Or do you think that re-using the wording "map" from #server-iris-to-http would be simpler and used more liberally.
