Looks great!

There’s no need to use a StringBuilder here.

    auto name = nodeName();
    return makeString(name.isEmpty() ? "<none>" : "", name, " 0x"_s, hex(reinterpret_cast<uintptr_t>(this), Lowercase));

There’s no need to use a StringBuilder here:

    if (isNull())
        return "<null>"_s;
    return makeString("offset ", m_offset, " of ", deprecatedNode()->debugDescription());

Again:

    return makeString("from offset ", m_start.offset(), " of ", startContainer().debugDescription(), " to offset ", m_end.offset(), " of ", endContainer().debugDescription());

One more time:

    if (isNone())
        return "<none>"_s;
    return makeString("from ", start().debugDescription(), " to ", end().debugDescription());
