Since our Lord Jesus Christ told us to avoid unnecessary repetitions in our prayers, what are the kinds of prayers we should then be praying without ceasing.
There is no way I can fully answer your question without also telling you the purpose of praying without ceasing.
The kind of prayers to pray without ceasing is the prayer for unbroken Communion with God. Maintaining an unbroken fellowship with God, every moment, holds great importance in the lives of the believers.
This kind of prayer enables God to continuously work in us both to will and to do of His good pleasure. We will be able to to make good decisions and choose to abey God in all situations because there will be conscious supply of power to obey from our spirit by the Holy Spirit. The Enemy, the world system, and even our Flesh are constantly working contrary working of God through our spirit to ensnare us out of the way of Life; to disobey God or compromise the truth.
Fellowship with God is a source of spiritual nourishment. Just as physical food sustains our bodies, regular communion with God through prayer, worship, and study of His Word nourishes our spirits. It deepens our understanding of His character, His will for our lives, and provides the guidance and wisdom we need to navigate life's challenges.

Through fellowship, individuals are transformed from the inside out, becoming more like Christ in character and actions.
Life can be filled with challenges, trials, and uncertainties. Maintaining fellowship with God provides strength and encouragement in times of difficulty. In His presence, believers find solace, peace, and a source of unwavering hope. The assurance of God's love and His promises fortify their hearts and enable them to persevere through adversity.
