Girsaot in Davening

Shalom aleichem Rabbi Lauffer. In some Ashkenazi siddurim the line in “l’olam yihei adam” is written זֶרַע יִצְחָק יְחִידו. שֶׁנֶּעֱקַד עַל גַּבֵּי הַמִּזְבֵּחַ
In other siddurim, the same line is written with “al gav hamizbeiach,” not “al gabei.” Again, in some siddurim the line in Tehillim 150 is written הַלְלוּהוּ בְּצִלְצְלֵי שָׁמַע. הַלְלוּהוּ בְּצִלְצְלֵי תְרוּעָה while in others it is written with a veis in the first “b’tziltzilei” and a beis in the second one. Lastly, in some siddurim it is written in the first blessing before Shema on Shabbos shacharis “שֶׁבַח יְקָר וּגְדֻלָּה. יִתְּנוּ לָאֵל מֶלֶךְ יוצֵר כּל. “La’el” is written, with a kometz under the first lamed, while in other siddurim a sh’va is under the same lamed. Which girsaos does Rabbi Lauffer use in his davening? Thanks a lot.
