Scholars are called “supporters of the Torah.” They enable the Torah study, even though they don’t personally study as many hours as the Torah scholars; so too, the wooden beams weren’t a direct part of the structure, they were only helping with the structural integrity of the stone walls and ceiling.
Also, we can clearly see that there is a great superiority in the Earth, which is the quality of how it is selflessness, it is the ground upon which all feet tread. Whereas the vegetable kingdom grows and exalts itself, and becomes damaged when stepped upon.
This selflessness is derived from its lofty source in Hashem’s “מ חֲש ָבָה-thought,” and the word “מ חֲש ָבָה” is made from two words “חָש ב־מ''ה-considers itself like nothing,” which shows on total selflessness.
This selflessness of the original “thought” is similar to what Moshe Rabeinu said about himself (Shemos16:7) “and we are ‘מָּ''ה-like nothing,’ since he was also on the level of the original thought of Hashem.
From there, (in its source in Hashem’s original thought) this total selflessness is drawn down and becomes expressed in the selflessness of the Earth.
Due to this, the lofty source of Malchus-Earth, in the Future Messianic Era it will elevated to be revealed as “the crown of her husband,” i.e., much higher than Ze’eir Anpin.
Therefore, the Beis HaMikdash was specifically built by using stones (to represent this spiritual dynamic).
In contrast, the Mishkan was constructed according to “Seder Hishtalshelus-spiritual hierarchy” of the current era, when the vegetable kingdom supersedes the inanimate kingdom, and “the Heavens precede the Earth.” Therefore, its walls were constructed from cedar beams, and the dirt materials were only used for the floor of the Mishkan, as was explained above.
