Revelation 2:7 is clearly talking to all churches in all generations. Jesus repeats this seven times for emphasis.
Revelation 2:7 He that hath an ear, let him hear what the Spirit saith unto the churches; To him that overcometh will I give to eat of the tree of life, which is in the midst of the paradise of God.

Pulpit Commentary on Revelation, page 56, The epistles to the seven churches.
Once more we have to consider rival interpretations. Of these we may safely set aside all those which make the seven letters to be pictures of successive periods in the history of the Church. On the other hand, we may safely deny that the letters are purely typical, and relate to nothing definite in history. Rather they are both historical and typical. They refer primarily to the actual condition of the several Churches in St John's own day, and then are intended for the instruction, encouragement, and warning of the Church and the Churches throughout all time.
William Henry Commentary, page 1971
A call to attention. What is said to one church concerns all churches, in every place and age.
Thomas Nelson King James Study Bible Second Edition, page 1902
The seven letters of chapters 2 and 3 may be interpreted various was:
- Historical—the letters should be understood historically, with no prophetic significance.
- Historo-prophetic—the letters are addressed to seven historical churches, but each church also represents a successive phase or period in history of professing Christendom.
- Representative—Each church contains characteristics that can be found to some degree in most churches throughout church history. These letters represent the "things which are" (Revelation 1:19). Thus, they are historical and representative [types], rather than prophetic.
Vincent Word Studies of the New Testament, pages 411-412
Seven churches. The seven churches are to symbolize the whole church (Revelation 2:7). Seven being the number of the covenant, we have in these seven a representation of the church universal.
The Wycliffe Bible Commentary, page 1504
[Regarding Laodicea] It seems that lukewarmness and indifference will mark the church at the end of the age, particularly indifference as to the great doctrines of the faith and unwillingness to defend them.

Blue Letter Bible Commentary: Clarence Larkin
The Book is addressed to the "seven churches which are in Asia." By Asia is not meant the great Continent of Asia, or even the whole of Asia Minor, but only its western end. Neither were the seven churches named the only churches in that district, for there were at least three other churches: Colosse,
Col. 1:2; Hierapolis,
Col. 4:13; and Troas,
Acts 20:6,
7.
These Seven Churches then must be representative or "typical" churches, chosen for certain characteristics typical of the character of the Church of Christ from the end of the First Century down to the time of Christ's return for His Church, and descriptive of clearly defined in Church History.
Zondervan Academic: The Seven Churches of Revelation
That the letters to the seven churches often betray characteristics of the cities in which these churches flourished reminds us how easily churches can reflect the values of their culture if we do not remain vigilant against those values.
Not all commentaries agree, but there is a general consensus on the seven churches also being types. Therefore, Laodicea is indeed indicative of the modern church, which clearly is lukewarm, but we don't need types to see that plain as day.
God bless!
