A National D-Visa is not a residence permit
A residence permit is treated as D-Visa insofar that it allows the holder to travel to other Schengen countries using the 90/180 rule.
Consulates generally do not issue residence permits.
A Consulate will issue a D-Visa based on their national laws
With a D-Visa you can enter the Schengen Area (if not geographicly restricted) at any port of entry and transit to the country that issued the visa.

The US embassy in Poland states exactly who can enter Poland (emphasis mine):
Only the following categories of travelers will be allowed to enter:
- Polish citizens
- Citizens and residents of European Union countries who are transiting Poland en route to their place of residence or stay
- Spouses and children of EU citizens and residents who are transiting Poland en route to their place of residence or stay
- Foreigners who are spouses or children of Polish citizens or remain under the constant care of Polish citizens
- Foreigners holding a Karta Polaka (ID card for those with a claim to Polish heritage through ancestry)
- Persons with diplomatic status and members of their families
- Foreigners who have the right of permanent or temporary residence in Poland
- Foreigners who have the right to work in Poland
- Foreigners who have work permits
- Foreigners who drive a vehicle used to transport goods
- Other particularly justified cases may be considered, but entry must be granted with the permission of the Chief of the Border Guard: https://www.strazgraniczna.pl/pl/kontakt/1946,Komenda-Glowna-Strazy-Granicznej.html
So since you have a work permit, you will be able to enter.
But since your questions is:
Is National Visa type D considered as resident permit or not?
I would say yes, but would not risk going to Poland only with that visa but would make sure I have something else that allows me to enter (like a work permit in your case).
