His reference to the Holy Spirit is to the source of power exhibited by the laying on of hands. Have you seen the power of God displayed through yourself or someone else in a significant way? And yet the same exhibit of His power doesn't always happen in that manner?
"It seemed good of the Holy Spirit" is not a reference to the Spirit having an opinion of His own, but rather showing that this laying on of hands exhibited the power of the Holy Spirit as well.
What we know of the Holy Spirit through the culmination of Scripture is that He always points towards the Father and of the Son, and never at Himself. We also know that He expressly and exclusively carries out the will of the Father and Son, particularly the Father's will, as He is the operations manager and planner of God, as described in Scripture.
John 15:26
"26 “But when the Helper comes, whom I shall send to you from the Father, the Spirit of truth who proceeds from the Father, He will testify of Me."
This verse is an example of many that describe the role the Holy Spirit plays in our lives in this world. He has His own will because He is also a Person of the Trinity (which Ozzie Ozzie incorrectly concludes He's not), but His acts of will and deed always reflect the operation manager's will, that is God the Father's.
Matthew 28:19, 20--
"19) Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20) teaching them to observe all things that I have commanded you; and lo, I am with you always, even to the end of the age. Amen."
Note the use of all persons, "names". of the trinity into which we are to baptize disciples? The Holy Spirit is an equal, but as the Son was submissive of His will to the Father, so the Spirit submits his will to both and acts on their behalf. Another example of the trinity ("Lord" as in the Lord Jesus Christ) in Scripture from
Ephesians 4:4-6
"4 There is one body and one Spirit, just as you were called in one hope of your calling; 5 one Lord, one faith, one baptism; 6 one God and Father of all, who is above all, and through all, and in [c]you all."
These next two show how although they are three persons, and equals, they have different roles and show that through submission.
Philippians 2:5-8
"5 Let this mind be in you which was also in Christ Jesus, 6 who, being in the form of God, did not consider it [b]robbery to be equal with God, 7 but [c]made Himself of no reputation, taking the form of a bondservant, and coming in the likeness of men. 8 And being found in appearance as a man, He humbled Himself and became obedient to the point of death, even the death of the cross."
Luke 22:41-44
"41 And He was withdrawn from them about a stone’s throw, and He knelt down and prayed, 42 saying, “Father, if it is Your will, take this cup away from Me; nevertheless not My will, but Yours, be done.” 43 [f]Then an angel appeared to Him from heaven, strengthening Him. 44 And being in agony, He prayed more earnestly. Then His sweat became like great drops of blood falling down to the ground."
Submission in the Trinity is par for the course. Submission is an illustration of Love and Faith and Power. Meekness is not weakness.
FINALLY. We see that the Holy Spirit, as I said before, is expressly communicating and doing per the will of the Father and the Son. So, His Counsel is not His own opinion, but rather the Father's opinion, the Father's will. Whatever the Spirit hears from the Father, that is what He's going to say to you.
John 16:12-15
"12 “I still have many things to say to you, but you cannot bear them now. 13 However, when He, the Spirit of truth, has come, He will guide you into all truth; for He will not speak on His own authority, but whatever He hears He will speak; and He will tell you things to come. 14 He will glorify Me, for He will take of what is Mine and declare it to you. 15 All things that the Father has are Mine. Therefore I said that He [c]will take of Mine and declare it to you."
